• What Constitutes Plagiarism?

In academic writing, it is considered plagiarism to draw any idea or any language from someone else without adequately crediting that source in your paper. It doesn't matter whether the source is a published author, another student, a website without clear authorship, a website that sells academic papers, or any other person: Taking credit for anyone else's work is stealing, and it is unacceptable in all academic situations, whether you do it intentionally or by accident.

The ease with which you can find information of all kinds online means that you need to be extra vigilant about keeping track of where you are getting information and ideas and about giving proper credit to the authors of the sources you use. If you cut and paste from an electronic document into your notes and forget to clearly label the document in your notes, or if you draw information from a series of websites without taking careful notes, you may end up taking credit for ideas that aren't yours, whether you mean to or not.

It's important to remember that every website is a document with an author, and therefore every website must be cited properly in your paper. For example, while it may seem obvious to you that an idea drawn from Professor Steven Pinker's book The Language Instinct should only appear in your paper if you include a clear citation, it might be less clear that information you glean about language acquisition from the Stanford Encyclopedia of Philosophy website warrants a similar citation. Even though the authorship of this encyclopedia entry is less obvious than it might be if it were a print article (you need to scroll down the page to see the author's name, and if you don't do so you might mistakenly think an author isn't listed), you are still responsible for citing this material correctly. Similarly, if you consult a website that has no clear authorship, you are still responsible for citing the website as a source for your paper. The kind of source you use, or the absence of an author linked to that source, does not change the fact that you always need to cite your sources (see Evaluating Web Sources ).

Verbatim Plagiarism

If you copy language word for word from another source and use that language in your paper, you are plagiarizing verbatim . Even if you write down your own ideas in your own words and place them around text that you've drawn directly from a source, you must give credit to the author of the source material, either by placing the source material in quotation marks and providing a clear citation, or by paraphrasing the source material and providing a clear citation.

The passage below comes from Ellora Derenoncourt’s article, “Can You Move to Opportunity? Evidence from the Great Migration.”

Here is the article citation in APA style:

Derenoncourt, E. (2022). Can you move to opportunity? Evidence from the Great Migration. The American Economic Review , 112(2), 369–408. https://doi.org/10.1257/aer.20200002

Source material

Why did urban Black populations in the North increase so dramatically between 1940 and 1970? After a period of reduced mobility during the Great Depression, Black out-migration from the South resumed at an accelerated pace after 1940. Wartime jobs in the defense industry and in naval shipyards led to substantial Black migration to California and other Pacific states for the first time since the Migration began. Migration continued apace to midwestern cities in the 1950s and1960s, as the booming automobile industry attracted millions more Black southerners to the North, particularly to cities like Detroit or Cleveland. Of the six million Black migrants who left the South during the Great Migration, four million of them migrated between 1940 and 1970 alone.

Plagiarized version

While this student has written her own sentence introducing the topic, she has copied the italicized sentences directly from the source material. She has left out two sentences from Derenoncourt’s paragraph, but has reproduced the rest verbatim:

But things changed mid-century. After a period of reduced mobility during the Great Depression, Black out-migration from the South resumed at an accelerated pace after 1940. Wartime jobs in the defense industry and in naval shipyards led to substantial Black migration to California and other Pacific states for the first time since the Migration began. Migration continued apace to midwestern cities in the 1950s and1960s, as the booming automobile industry attracted millions more Black southerners to the North, particularly to cities like Detroit or Cleveland.

Acceptable version #1: Paraphrase with citation

In this version the student has paraphrased Derenoncourt’s passage, making it clear that these ideas come from a source by introducing the section with a clear signal phrase ("as Derenoncourt explains…") and citing the publication date, as APA style requires.

But things changed mid-century. In fact, as Derenoncourt (2022) explains, the wartime increase in jobs in both defense and naval shipyards marked the first time during the Great Migration that Black southerners went to California and other west coast states. After the war, the increase in jobs in the car industry led to Black southerners choosing cities in the midwest, including Detroit and Cleveland.

Acceptable version #2 : Direct quotation with citation or direct quotation and paraphrase with citation

If you quote directly from an author and cite the quoted material, you are giving credit to the author. But you should keep in mind that quoting long passages of text is only the best option if the particular language used by the author is important to your paper. Social scientists and STEM scholars rarely quote in their writing, paraphrasing their sources instead. If you are writing in the humanities, you should make sure that you only quote directly when you think it is important for your readers to see the original language.

In the example below, the student quotes part of the passage and paraphrases the rest.

But things changed mid-century. In fact, as Derenoncourt (2022) explains, “after a period of reduced mobility during the Great Depression, Black out-migration from the South resumed at an accelerated pace after 1940” (p. 379). Derenoncourt notes that after the war, the increase in jobs in the car industry led to Black southerners choosing cities in the midwest, including Detroit and Cleveland.

Mosaic Plagiarism

If you copy bits and pieces from a source (or several sources), changing a few words here and there without either adequately paraphrasing or quoting directly, the result is mosaic plagiarism . Even if you don't intend to copy the source, you may end up with this type of plagiarism as a result of careless note-taking and confusion over where your source's ideas end and your own ideas begin. You may think that you've paraphrased sufficiently or quoted relevant passages, but if you haven't taken careful notes along the way, or if you've cut and pasted from your sources, you can lose track of the boundaries between your own ideas and those of your sources. It's not enough to have good intentions and to cite some of the material you use. You are responsible for making clear distinctions between your ideas and the ideas of the scholars who have informed your work. If you keep track of the ideas that come from your sources and have a clear understanding of how your own ideas differ from those ideas, and you follow the correct citation style, you will avoid mosaic plagiarism.

Indeed, of the more than 3500 hours of instruction during medical school, an average of less than 60 hours are devoted to all of bioethics, health law and health economics combined . Most of the instruction is during the preclinical courses, leaving very little instructional time when students are experiencing bioethical or legal challenges during their hands-on, clinical training. More than 60 percent of the instructors in bioethics, health law, and health economics have not published since 1990 on the topic they are teaching.

--Persad, G.C., Elder, L., Sedig,L., Flores, L., & Emanuel, E. (2008). The current state of medical school education in bioethics, health law, and health economics. Journal of Law, Medicine, and Ethics 36 , 89-94.

Students can absorb the educational messages in medical dramas when they view them for entertainment. In fact, even though they were not created specifically for education, these programs can be seen as an entertainment-education tool [43, 44]. In entertainment-education shows, viewers are exposed to educational content in entertainment contexts, using visual language that is easy to understand and triggers emotional engagement [45]. The enhanced emotional engagement and cognitive development [5] and moral imagination make students more sensitive to training [22].

--Cambra-Badii, I., Moyano, E., Ortega, I., Josep-E Baños, & Sentí, M. (2021). TV medical dramas: Health sciences students’ viewing habits and potential for teaching issues related to bioethics and professionalism. BMC Medical Education, 21 , 1-11. doi: https://doi.org/10.1186/s12909-021-02947-7

Paragraph #1.

All of the ideas in this paragraph after the first sentence are drawn directly from Persad. But because the student has placed the citation mid-paragraph, the final two sentences wrongly appear to be the student’s own idea:

In order to advocate for the use of medical television shows in the medical education system, it is also important to look at the current bioethical curriculum. In the more than 3500 hours of training that students undergo in medical school, only about 60 hours are focused on bioethics, health law, and health economics (Persad et al, 2008). It is also problematic that students receive this training before they actually have spent time treating patients in the clinical setting. Most of these hours are taught by instructors without current publications in the field.

Paragraph #2.

All of the italicized ideas in this paragraph are either paraphrased or taken verbatim from Cambra-Badii, et al., but the student does not cite the source at all. As a result, readers will assume that the student has come up with these ideas himself:

Students can absorb the educational messages in medical dramas when they view them for entertainment. It doesn’t matter if the shows were designed for medical students; they can still be a tool for education. In these hybrid entertainment-education shows, viewers are exposed to educational content that triggers an emotional reaction. By allowing for this emotional, cognitive, and moral engagement, the shows make students more sensitive to training . There may be further applications to this type of education: the role of entertainment as a way of encouraging students to consider ethical situations could be extended to other professions, including law or even education.

The student has come up with the final idea in the paragraph (that this type of ethical training could apply to other professions), but because nothing in the paragraph is cited, it reads as if it is part of a whole paragraph of his own ideas, rather than the point that he is building to after using the ideas from the article without crediting the authors.

Acceptable version

In the first paragraph, the student uses signal phrases in nearly every sentence to reference the authors (“According to Persad et al.,” “As the researchers argue,” “They also note”), which makes it clear throughout the paragraph that all of the paragraph’s information has been drawn from Persad et al. The student also uses a clear APA in-text citation to point the reader to the original article. In the second paragraph, the student paraphrases and cites the source’s ideas and creates a clear boundary behind those ideas and his own, which appear in the final paragraph.

In order to advocate for the use of medical television shows in the medical education system, it is also important to look at the current bioethical curriculum. According to Persad et al. (2008), only about one percent of teaching time throughout the four years of medical school is spent on ethics. As the researchers argue, this presents a problem because the students are being taught about ethical issues before they have a chance to experience those issues themselves. They also note that more than sixty percent of instructors teaching bioethics to medical students have no recent publications in the subject.

The research suggests that medical dramas may be a promising source for discussions of medical ethics. Cambra-Badii et al. (2021) explain that even when watched for entertainment, medical shows can help viewers engage emotionally with the characters and may prime them to be more receptive to training in medical ethics. There may be further applications to this type of education: the role of entertainment as a way of encouraging students to consider ethical situations could be extended to other professions, including law or even education.

Inadequate Paraphrase

When you paraphrase, your task is to distill the source's ideas in your own words. It's not enough to change a few words here and there and leave the rest; instead, you must completely restate the ideas in the passage in your own words. If your own language is too close to the original, then you are plagiarizing, even if you do provide a citation.

In order to make sure that you are using your own words, it's a good idea to put away the source material while you write your paraphrase of it. This way, you will force yourself to distill the point you think the author is making and articulate it in a new way. Once you have done this, you should look back at the original and make sure that you have represented the source’s ideas accurately and that you have not used the same words or sentence structure. If you do want to use some of the author's words for emphasis or clarity, you must put those words in quotation marks and provide a citation.

The passage below comes from Michael Sandel’s article, “The Case Against Perfection.” Here’s the article citation in MLA style:

Sandel, Michael. “The Case Against Perfection.” The Atlantic , April 2004, https://www.theatlantic.com/magazine/archive/2004/04/the-case-against-pe... .

Though there is much to be said for this argument, I do not think the main problem with enhancement and genetic engineering is that they undermine effort and erode human agency. The deeper danger is that they represent a kind of hyperagency—a Promethean aspiration to remake nature, including human nature, to serve our purposes and satisfy our desires. The problem is not the drift to mechanism but the drive to mastery. And what the drive to mastery misses and may even destroy is an appreciation of the gifted character of human powers and achievements.

The version below is an inadequate paraphrase because the student has only cut or replaced a few words: “I do not think the main problem” became “the main problem is not”; “deeper danger” became “bigger problem”; “aspiration” became “desire”; “the gifted character of human powers and achievements” became “the gifts that make our achievements possible.”

The main problem with enhancement and genetic engineering is not that they undermine effort and erode human agency. The bigger problem is that they represent a kind of hyperagency—a Promethean desire to remake nature, including human nature, to serve our purposes and satisfy our desires. The problem is not the drift to mechanism but the drive to mastery. And what the drive to mastery misses and may even destroy is an appreciation of the gifts that make our achievements possible (Sandel).

Acceptable version #1: Adequate paraphrase with citation

In this version, the student communicates Sandel’s ideas but does not borrow language from Sandel. Because the student uses Sandel’s name in the first sentence and has consulted an online version of the article without page numbers, there is no need for a parenthetical citation.

Michael Sandel disagrees with the argument that genetic engineering is a problem because it replaces the need for humans to work hard and make their own choices. Instead, he argues that we should be more concerned that the decision to use genetic enhancement is motivated by a desire to take control of nature and bend it to our will instead of appreciating its gifts.

Acceptable version #2: Direct quotation with citation

In this version, the student uses Sandel’s words in quotation marks and provides a clear MLA in-text citation. In cases where you are going to talk about the exact language that an author uses, it is acceptable to quote longer passages of text. If you are not going to discuss the exact language, you should paraphrase rather than quoting extensively.

The author argues that “the main problem with enhancement and genetic engineering is not that they undermine effort and erode human agency,” but, rather that “they represent a kind of hyperagency—a Promethean desire to remake nature, including human nature, to serve our purposes and satisfy our desires. The problem is not the drift to mechanism but the drive to mastery. And what the drive to mastery misses and may even destroy is an appreciation of the gifts that make our achievements possible” (Sandel).

Uncited Paraphrase

When you use your own language to describe someone else's idea, that idea still belongs to the author of the original material. Therefore, it's not enough to paraphrase the source material responsibly; you also need to cite the source, even if you have changed the wording significantly. As with quoting, when you paraphrase you are offering your reader a glimpse of someone else's work on your chosen topic, and you should also provide enough information for your reader to trace that work back to its original form. The rule of thumb here is simple: Whenever you use ideas that you did not think up yourself, you need to give credit to the source in which you found them, whether you quote directly from that material or provide a responsible paraphrase.

The passage below comes from C. Thi Nguyen’s article, “Echo Chambers and Epistemic Bubbles.”

Here’s the citation for the article, in APA style:

Nguyen, C. (2020). Echo chambers and epistemic bubbles. Episteme, 17 (2), 141-161. doi:10.1017/epi.2018.32

Epistemic bubbles can easily form accidentally. But the most plausible explanation for the particular features of echo chambers is something more malicious. Echo chambers are excellent tools to maintain, reinforce, and expand power through epistemic control. Thus, it is likely (though not necessary) that echo chambers are set up intentionally, or at least maintained, for this functionality (Nguyen, 2020).

The student who wrote the paraphrase below has drawn these ideas directly from Nguyen’s article but has not credited the author. Although she paraphrased adequately, she is still responsible for citing Nguyen as the source of this information.

Echo chambers and epistemic bubbles have different origins. While epistemic bubbles can be created organically, it’s more likely that echo chambers will be formed by those who wish to keep or even grow their control over the information that people hear and understand.

In this version, the student eliminates any possible ambiguity about the source of the ideas in the paragraph. By using a signal phrase to name the author whenever the source of the ideas could be unclear, the student clearly attributes these ideas to Nguyen.

According to Nguyen (2020), echo chambers and epistemic bubbles have different origins. Nguyen argues that while epistemic bubbles can be created organically, it’s more likely that echo chambers will be formed by those who wish to keep or even grow their control over the information that people hear and understand.

Uncited Quotation

When you put source material in quotation marks in your essay, you are telling your reader that you have drawn that material from somewhere else. But it's not enough to indicate that the material in quotation marks is not the product of your own thinking or experimentation: You must also credit the author of that material and provide a trail for your reader to follow back to the original document. This way, your reader will know who did the original work and will also be able to go back and consult that work if they are interested in learning more about the topic. Citations should always go directly after quotations.

The passage below comes from Deirdre Mask’s nonfiction book, The Address Book: What Street Addresses Reveal About Identity, Race, Wealth, and Power.

Here is the MLA citation for the book:

Mask, Deirdre. The Address Book: What Street Addresses Reveal About Identity, Race, Wealth, and Power. St. Martin’s Griffin, 2021.

In New York, even addresses are for sale. The city allows a developer, for the bargain price of $11,000 (as of 2019), to apply to change the street address to something more attractive.

It’s not enough for the student to indicate that these words come from a source; the source must be cited:

After all, “in New York, even addresses are for sale. The city allows a developer, for the bargain price of $11,000 (as of 2019), to apply to change the street address to something more attractive.”

Here, the student has cited the source of the quotation using an MLA in-text citation:

After all, “in New York, even addresses are for sale. The city allows a developer, for the bargain price of $11,000 (as of 2019), to apply to change the street address to something more attractive” (Mask 229).

Using Material from Another Student's Work

In some courses you will be allowed or encouraged to form study groups, to work together in class generating ideas, or to collaborate on your thinking in other ways. Even in those cases, it's imperative that you understand whether all of your writing must be done independently, or whether group authorship is permitted. Most often, even in courses that allow some collaborative discussion, the writing or calculations that you do must be your own. This doesn't mean that you shouldn't collect feedback on your writing from a classmate or a writing tutor; rather, it means that the argument you make (and the ideas you rely on to make it) should either be your own or you should give credit to the source of those ideas.

So what does this mean for the ideas that emerge from class discussion or peer review exercises? Unlike the ideas that your professor offers in lecture (you should always cite these), ideas that come up in the course of class discussion or peer review are collaborative, and often not just the product of one individual's thinking. If, however, you see a clear moment in discussion when a particular student comes up with an idea, you should cite that student. In any case, when your work is informed by class discussions, it's courteous and collegial to include a discursive footnote in your paper that lets your readers know about that discussion. So, for example, if you were writing a paper about the narrator in Tim O'Brien's The Things They Carried and you came up with your idea during a discussion in class, you might place a footnote in your paper that states the following: "I am indebted to the members of my Expos 20 section for sparking my thoughts about the role of the narrator as Greek Chorus in Tim O'Brien's The Things They Carried ."

It is important to note that collaboration policies can vary by course, even within the same department, and you are responsible for familiarizing yourself with each course's expectation about collaboration. Collaboration policies are often stated in the syllabus, but if you are not sure whether it is appropriate to collaborate on work for any course, you should always consult your instructor.

Information about what plagiarism is, and how you can avoid it.

The University defines plagiarism as follows:

“Presenting work or ideas from another source as your own, with or without consent of the original author, by incorporating it into your work without full acknowledgement. All published and unpublished material, whether in manuscript, printed or electronic form, is covered under this definition, as is the use of material generated wholly or in part through use of artificial intelligence (save when use of AI for assessment has received prior authorisation e.g. as a reasonable adjustment for a student’s disability). Plagiarism can also include re-using your own work without citation. Under the regulations for examinations, intentional or reckless plagiarism is a disciplinary offence.”

The necessity to acknowledge others’ work or ideas applies not only to text, but also to other media, such as computer code, illustrations, graphs etc. It applies equally to published text and data drawn from books and journals, and to unpublished text and data, whether from lectures, theses or other students’ essays. You must also attribute text, data, or other resources downloaded from websites.

Please note that artificial intelligence (AI) can only be used within assessments where specific prior authorisation has been given, or when technology that uses AI has been agreed as reasonable adjustment for a student’s disability (such as voice recognition software for transcriptions, or spelling and grammar checkers).

The best way of avoiding plagiarism is to learn and employ the principles of good academic practice from the beginning of your university career. Avoiding plagiarism is not simply a matter of making sure your references are all correct, or changing enough words so the examiner will not notice your paraphrase; it is about deploying your academic skills to make your work as good as it can be.

Students will benefit from taking an  online course  which has been developed to provide a useful overview of the issues surrounding plagiarism and practical ways to avoid it.

Forms of plagiarism

Verbatim (word for word) quotation without clear acknowledgement Quotations must always be identified as such by the use of either quotation marks or indentation, and with full referencing of the sources cited. It must always be apparent to the reader which parts are your own independent work and where you have drawn on ideas and language from another source.

Cutting and pasting from the Internet without clear acknowledgement Information derived from the Internet must be adequately referenced and included in the bibliography. It is important to evaluate carefully all material found on the Internet, as it is less likely to have been through the same process of scholarly peer review as published sources.

Paraphrasing Paraphrasing the work of others by altering a few words and changing their order, or by closely following the structure of their argument, is plagiarism if you do not give due acknowledgement to the author whose work you are using.

A passing reference to the original author in your own text may not be enough; you must ensure that you do not create the misleading impression that the paraphrased wording or the sequence of ideas are entirely your own. It is better to write a brief summary of the author’s overall argument in your own words, indicating that you are doing so, than to paraphrase particular sections of his or her writing. This will ensure you have a genuine grasp of the argument and will avoid the difficulty of paraphrasing without plagiarising. You must also properly attribute all material you derive from lectures.

Collusion This can involve unauthorised collaboration between students, failure to attribute assistance received, or failure to follow precisely regulations on group work projects. It is your responsibility to ensure that you are entirely clear about the extent of collaboration permitted, and which parts of the work must be your own.

Inaccurate citation It is important to cite correctly, according to the conventions of your discipline. As well as listing your sources (i.e. in a bibliography), you must indicate, using a footnote or an in-text reference, where a quoted passage comes from. Additionally, you should not include anything in your references or bibliography that you have not actually consulted. If you cannot gain access to a primary source you must make it clear in your citation that your knowledge of the work has been derived from a secondary text (for example, Bradshaw, D. Title of Book, discussed in Wilson, E., Title of Book (London, 2004), p. 189).

Failure to acknowledge assistance You must clearly acknowledge all assistance which has contributed to the production of your work, such as advice from fellow students, laboratory technicians, and other external sources. This need not apply to the assistance provided by your tutor or supervisor, or to ordinary proofreading, but it is necessary to acknowledge other guidance which leads to substantive changes of content or approach.

Use of material written by professional agencies or other persons You should neither make use of professional agencies in the production of your work nor submit material which has been written for you even with the consent of the person who has written it. It is vital to your intellectual training and development that you should undertake the research process unaided. Under Statute XI on University Discipline, all members of the University are prohibited from providing material that could be submitted in an examination by students at this University or elsewhere.

Auto-plagiarism You must not submit work for assessment that you have already submitted (partially or in full), either for your current course or for another qualification of this, or any other, university, unless this is specifically provided for in the special regulations for your course. Where earlier work by you is citable, i.e. it has already been published, you must reference it clearly. Identical pieces of work submitted concurrently will also be considered to be auto-plagiarism.

Why does plagiarism matter?

Plagiarism is a breach of academic integrity. It is a principle of intellectual honesty that all members of the academic community should acknowledge their debt to the originators of the ideas, words, and data which form the basis for their own work. Passing off another’s work as your own is not only poor scholarship, but also means that you have failed to complete the learning process. Plagiarism is unethical and can have serious consequences for your future career; it also undermines the standards of your institution and of the degrees it issues.

Why should you avoid plagiarism?

There are many reasons to avoid plagiarism. You have come to university to learn to know and speak your own mind, not merely to reproduce the opinions of others - at least not without attribution. At first it may seem very difficult to develop your own views, and you will probably find yourself paraphrasing the writings of others as you attempt to understand and assimilate their arguments. However it is important that you learn to develop your own voice. You are not necessarily expected to become an original thinker, but you are expected to be an independent one - by learning to assess critically the work of others, weigh up differing arguments and draw your own conclusions. Students who plagiarise undermine the ethos of academic scholarship while avoiding an essential part of the learning process.

You should avoid plagiarism because you aspire to produce work of the highest quality. Once you have grasped the principles of source use and citation, you should find it relatively straightforward to steer clear of plagiarism. Moreover, you will reap the additional benefits of improvements to both the lucidity and quality of your writing. It is important to appreciate that mastery of the techniques of academic writing is not merely a practical skill, but one that lends both credibility and authority to your work, and demonstrates your commitment to the principle of intellectual honesty in scholarship.

What happens if you are thought to have plagiarised?

The University regards plagiarism in examinations as a serious matter. Cases will be investigated and penalties may range from deduction of marks to expulsion from the University, depending on the seriousness of the occurrence. Even if plagiarism is inadvertent, it can result in a penalty. The forms of plagiarism listed above are all potentially disciplinary offences in the context of formal assessment requirements.

The regulations regarding conduct in examinations apply equally to the ‘submission and assessment of a thesis, dissertation, essay, or other coursework not undertaken in formal examination conditions but which counts towards or constitutes the work for a degree or other academic award’. Additionally, this includes the transfer and confirmation of status exercises undertaken by graduate students. Cases of suspected plagiarism in assessed work are investigated under the disciplinary regulations concerning conduct in examinations. Intentional plagiarism in this context means that you understood that you were breaching the regulations and did so intending to gain advantage in the examination. Reckless, in this context, means that you understood or could be expected to have understood (even if you did not specifically consider it) that your work might breach the regulations, but you took no action to avoid doing so. Intentional or reckless plagiarism may incur severe penalties, including failure of your degree or expulsion from the university.

If plagiarism is suspected in a piece of work submitted for assessment in an examination, the matter will be referred to the Proctors. They will thoroughly investigate the claim and call the student concerned for interview. If at this point there is no evidence of a breach of the regulations, no further disciplinary action will be taken although there may still be an academic penalty. However, if it is concluded that a breach of the regulations may have occurred, the Proctors will refer the case to the Student Disciplinary Panel.

If you are suspected of plagiarism your College Secretary/Academic Administrator and subject tutor will support you through the process and arrange for a member of Congregation to accompany you to all hearings. They will be able to advise you what to expect during the investigation and how best to make your case. The Oxford SU Student Advice Service can also provide useful information and support. 

Does this mean that I shouldn’t use the work of other authors?

On the contrary, it is vital that you situate your writing within the intellectual debates of your discipline. Academic essays almost always involve the use and discussion of material written by others, and, with due acknowledgement and proper referencing, this is clearly distinguishable from plagiarism. The knowledge in your discipline has developed cumulatively as a result of years of research, innovation and debate. You need to give credit to the authors of the ideas and observations you cite. Not only does this accord recognition to their work, it also helps you to strengthen your argument by making clear the basis on which you make it. Moreover, good citation practice gives your reader the opportunity to follow up your references, or check the validity of your interpretation.

Does every statement in my essay have to be backed up with references?

You may feel that including the citation for every point you make will interrupt the flow of your essay and make it look very unoriginal. At least initially, this may sometimes be inevitable. However, by employing good citation practice from the start, you will learn to avoid errors such as close paraphrasing or inadequately referenced quotation. It is important to understand the reasons behind the need for transparency of source use.

All academic texts, even student essays, are multi-voiced, which means they are filled with references to other texts. Rather than attempting to synthesise these voices into one narrative account, you should make it clear whose interpretation or argument you are employing at any one time - whose ‘voice’ is speaking.

If you are substantially indebted to a particular argument in the formulation of your own, you should make this clear both in footnotes and in the body of your text according to the agreed conventions of the discipline, before going on to describe how your own views develop or diverge from this influence.

On the other hand, it is not necessary to give references for facts that are common knowledge in your discipline. If you are unsure as to whether something is considered to be common knowledge or not, it is safer to cite it anyway and seek clarification. You do need to document facts that are not generally known and ideas that are interpretations of facts. 

Does this only matter in exams?

Although plagiarism in weekly essays does not constitute a University disciplinary offence, it may well lead to College disciplinary measures. Persistent academic under-performance can even result in your being sent down from the University. Although tutorial essays traditionally do not require the full scholarly apparatus of footnotes and referencing, it is still necessary to acknowledge your sources and demonstrate the development of your argument, usually by an in-text reference. Many tutors will ask that you do employ a formal citation style early on, and you will find that this is good preparation for later project and dissertation work. In any case, your work will benefit considerably if you adopt good scholarly habits from the start, together with the techniques of critical thinking and writing described above.

As junior members of the academic community, students need to learn how to read academic literature and how to write in a style appropriate to their discipline. This does not mean that you must become masters of jargon and obfuscation; however the process is akin to learning a new language. It is necessary not only to learn new terminology, but the practical study skills and other techniques which will help you to learn effectively.

Developing these skills throughout your time at university will not only help you to produce better coursework, dissertations, projects and exam papers, but will lay the intellectual foundations for your future career. Even if you have no intention of becoming an academic, being able to analyse evidence, exercise critical judgement, and write clearly and persuasively are skills that will serve you for life, and which any employer will value.

Borrowing essays from other students to adapt and submit as your own is plagiarism, and will develop none of these necessary skills, holding back your academic development. Students who lend essays for this purpose are doing their peers no favours.

Unintentional plagiarism

Not all cases of plagiarism arise from a deliberate intention to cheat. Sometimes students may omit to take down citation details when taking notes, or they may be genuinely ignorant of referencing conventions. However, these excuses offer no sure protection against a charge of plagiarism. Even in cases where the plagiarism is found to have been neither intentional nor reckless, there may still be an academic penalty for poor practice.

It is your responsibility to find out the prevailing referencing conventions in your discipline, to take adequate notes, and to avoid close paraphrasing. If you are offered induction sessions on plagiarism and study skills, you should attend. Together with the advice contained in your subject handbook, these will help you learn how to avoid common errors. If you are undertaking a project or dissertation you should ensure that you have information on plagiarism and collusion. If ever in doubt about referencing, paraphrasing or plagiarism, you have only to ask your tutor.

Examples of plagiarism

There are some helpful examples of plagiarism-by-paraphrase and you will also find extensive advice on the referencing and library skills pages.

The following examples demonstrate some of the common pitfalls to avoid. These examples use the referencing system prescribed by the History Faculty but should be of use to students of all disciplines.

Source text

From a class perspective this put them [highwaymen] in an ambivalent position. In aspiring to that proud, if temporary, status of ‘Gentleman of the Road’, they did not question the inegalitarian hierarchy of their society. Yet their boldness of act and deed, in putting them outside the law as rebellious fugitives, revivified the ‘animal spirits’ of capitalism and became an essential part of the oppositional culture of working-class London, a serious obstacle to the formation of a tractable, obedient labour force. Therefore, it was not enough to hang them – the values they espoused or represented had to be challenged.

(Linebaugh, P., The London Hanged: Crime and Civil Society in the Eighteenth Century (London, 1991), p. 213. [You should give the reference in full the first time you use it in a footnote; thereafter it is acceptable to use an abbreviated version, e.g. Linebaugh, The London Hanged, p. 213.]

Plagiarised

• Although they did not question the inegalitarian hierarchy of their society, highwaymen became an essential part of the oppositional culture of working-class London, posing a serious threat to the formation of a biddable labour force. (This is a patchwork of phrases copied verbatim from the source, with just a few words changed here and there. There is no reference to the original author and no indication that these words are not the writer’s own.)
• Although they did not question the inegalitarian hierarchy of their society, highwaymen exercised a powerful attraction for the working classes. Some historians believe that this hindered the development of a submissive workforce. (This is a mixture of verbatim copying and acceptable paraphrase. Although only one phrase has been copied from the source, this would still count as plagiarism. The idea expressed in the first sentence has not been attributed at all, and the reference to ‘some historians’ in the second is insufficient. The writer should use clear referencing to acknowledge all ideas taken from other people’s work.)
• Although they did not question the inegalitarian hierarchy of their society, highwaymen ‘became an essential part of the oppositional culture of working-class London [and] a serious obstacle to the formation of a tractable, obedient labour force’.1 (This contains a mixture of attributed and unattributed quotation, which suggests to the reader that the first line is original to this writer. All quoted material must be enclosed in quotation marks and adequately referenced.)
• Highwaymen’s bold deeds ‘revivified the “animal spirits” of capitalism’ and made them an essential part of the oppositional culture of working-class London.1 Peter Linebaugh argues that they posed a major obstacle to the formation of an obedient labour force. (Although the most striking phrase has been placed within quotation marks and correctly referenced, and the original author is referred to in the text, there has been a great deal of unacknowledged borrowing. This should have been put into the writer’s own words instead.)
• By aspiring to the title of ‘Gentleman of the Road’, highwaymen did not challenge the unfair taxonomy of their society. Yet their daring exploits made them into outlaws and inspired the antagonistic culture of labouring London, forming a grave impediment to the development of a submissive workforce. Ultimately, hanging them was insufficient – the ideals they personified had to be discredited.1 (This may seem acceptable on a superficial level, but by imitating exactly the structure of the original passage and using synonyms for almost every word, the writer has paraphrased too closely. The reference to the original author does not make it clear how extensive the borrowing has been. Instead, the writer should try to express the argument in his or her own words, rather than relying on a ‘translation’ of the original.)

Non-plagiarised

• Peter Linebaugh argues that although highwaymen posed no overt challenge to social orthodoxy – they aspired to be known as ‘Gentlemen of the Road’ – they were often seen as anti-hero role models by the unruly working classes. He concludes that they were executed not only for their criminal acts, but in order to stamp out the threat of insubordinacy.1 (This paraphrase of the passage is acceptable as the wording and structure demonstrate the reader’s interpretation of the passage and do not follow the original too closely. The source of the ideas under discussion has been properly attributed in both textual and footnote references.)
• Peter Linebaugh argues that highwaymen represented a powerful challenge to the mores of capitalist society and inspired the rebelliousness of London’s working class.1 (This is a brief summary of the argument with appropriate attribution.) 1 Linebaugh, P., The London Hanged: Crime and Civil Society in the Eighteenth Century (London, 1991), p. 213.

Plagiarism Guide

Table of content.

• 01. Types of Plagiarism
• 02. Consequences
• 03. How to Avoid Plagiarism
• 04. How to Cite Sources
• 05. How to Detect Plagiarism

If every student had a plagiarism guide, they would be able to avoid a whole array of problems with their college or university assignments. But unfortunately, only some of them seek out the rules, and even then, they don’t always understand what they should do and which mistakes to avoid. To help you learn everything there is to know about plagiarism, we developed an academic guide. After reading it, you won’t have any questions left, and your papers will be totally original. 

Plagiarism is the usage of ideas and words belonging to someone else coupled with failure to cite the name of this person. It is a common problem for students, and the worst thing is, you might not steal anything deliberately yet still end up in trouble. But hopefully, this guide will clear your confusion!

4 Major Types of Plagiarism

The first thing students should know is how many types of plagiarism can infect their research paper. There are four major ones, and they range from direct stealing to accidental borrowing. Take a look at the table below and try to remember them. We situated them in terms of their relevance, with less serious types being introduced first.

Consequences of Plagiarism

If professors catch their students plagiarizing, things will quickly speed up into disaster. Universities consider this a severe disruption of their academic demands, so the punishment is equally strict. Of course, you wouldn’t want to worry yourself even more, but it is important to know what danger you might be facing.

• Failing your studies.  If plagiarism detection tool caught its traces in your work, one of the likeliest outcomes is failure of the entire course. All your previous work will be annulled, no matter how successful or original it was, and you will have to repeat this year of studies from the start.
• Being suspended or expelled.  Sometimes, if your plagiarism was severe enough, you won’t have a chance to retake the course. You could be expelled right away, with your mistake being cited in your records.
• Legal problems.  There is such thing as copyright infringement. If your content is not original and you took it from someone who learned about it and filed a complaint, you risk facing legal repercussions. The complainer might sue you or demand payment, all of which will increase your anxiety and create even more problems.
• Destroyed reputation.  Your academic, professional, and personal reputation might be destroyed. Plagiarism usually means that you are not fit to be a specialist because you lack ideas and take them from others. So by plagiarizing once, you might taint your future victories for years, if not forever.

How to Avoid Plagiarism: 5 Vital Tips

If you want to make sure that your academic content is fully original, there are five different ways in which you could do it. We listed them all below, providing useful explanations. Take a look and apply at least some of these strategies: it’ll be enough to produce clean papers.

Always Use a Plagiarism Checker Tool

When students are done  checking their essays , they should choose one of plagiarism tools to check how original their text is. It’s even better to use several of them for getting the most accurate results. There are plenty of free options available, and some of them are detailed enough to let you know which sentences are problematic and how to reduce similarity rate.

Write by Yourself

The most guaranteed way of avoiding plagiarism is to write content in your own words. Brainstorm;  find an essay topic  you really like, and you’ll know what to say about it. This tip is closely connected with the one below.

Never Copy Anything from the Internet

Yes, you may use some universal ideas you stumbled across online, but never copy any sentence or revelation directly. Even if students just gather info before re-writing it in their words, it is still dangerous. They could forget which bit is copied and end up plagiarizing it by accident.  

Cite Your Sources Properly

When you use information that is not general knowledge, cite it. If you quote someone or re-tell their ideas, mention where they came from. You must do this for every unique idea that is not your own — not to mention you should follow all formatting style rules.

Check Copyright When Using Someone’s Ideas

There are million sites with interesting as well as useful information. Lots of students read articles or other academic publications, and very often, they get inspired enough to use them in papers. But even when you cite everything, you could still get into trouble. For preventing this, be sure you check whether the author allowed using their data. This will be mentioned somewhere on their site, usually in ‘terms of use’ category.

How to Cite Sources Correctly?

First of all, students should understand which claims must be cited. When you’re discussing usual ideas everyone knows about, you can do it without relying on anything. For example, you can talk about how many people live in poverty — this is a universal fact. But when you say that over 86% of people in India need financial assistance, it’s too specific, so citation is required. Are you wondering how to do it? No worries, we’re about to illustrate it.

There are lots of formatting styles, such as APA, MLA, Chicago, Harvard, and others. Some of them are used mostly in technical subjects like Math, others are applied in the sphere of Law, and the rest are preferred by Sociology and Psychology experts. Check instructions for seeing which style you need and what layout it has. Some document formats require a title page, others don’t; some need you to mention the name of the author and page number, others are more interested in the name and publication date. APA demands in-text citations while Chicago requires footnotes and endnotes.

Remember about fake referencing: this falls into the same category as plagiarism. If you take info from a book or an article, cite a specific page. Don’t make stuff up and add fake pages to create artificial citation — if you are caught, you’ll face the same penalty as with aforementioned plagiarism kinds. Cite a true page with a real author’s name and date. Be sure to do that both in the text and in a reference list: if you forget either, your citation won’t count.

Here are two examples with citations for the most popular style, MLA and APA.

In-text citation:

Some people believed that phobias are merely a social construct (Howard 32).

Work cited list citation:

Howard, Kevin.  Responding to Shifts in Society . Spencers Publishing, 2013.   

Having birds for pets has been proven to soothe anxiety and increase serotonin level (Lanes, 2018, p. 13).

Lanes, K. (2018). “Pets are the best therapy.”  Animals in Medicine ,  3 (4), 23-56. https://doi.org/1016.

How to Detect Plagiarism and Use Plag Checkers Effectively?

Professors are used to detecting plagiarism after merely looking through papers. They quickly notice if your style differs from paragraph to paragraph, not to mention they look at a language level. If students usually use simple vocabulary and suddenly their text becomes professional and refined, it’s suspicious. Plag checkers are vital, too, as professors pass most works through them. If you want to succeed, you should know how to use them yourself.

Look for the  best plagiarism checkers  that not just show a plagiarism rate, but which also underline the borrowed bits for you to see. You’ll see the links to sources where the plag checker believes you took info from, so you’ll have a chance to remove any copied stuff. Some developed checkers will even offer advice on how to correct problems — for example, they’ll show synonyms for individual words. Like we said above, try using several tools at once because their work is not perfect. This will allow synchronizing results and bringing plag rate to a minimum, avoiding committing plagiarism.

What Is Plagiarism: Your Checklist

• I understood my assigned formatting style and know how to cite information.
• When including a direct quote from someone, I put it into quotation marks & cited their name with the correct page number.
• When explaining others’ ideas, I paragraphed them effectively and cited a source.
• Each cited piece of info corresponds to the source I claim to use.
• I put my essay through plag checker & corrected any possible issues it caught.

What are the 4 types of plagiarism?

There are copy-paste, mosaic, global, as well as self-plagiarism. If someone copies text directly, it’s copy-paste. If they drag different bits from different texts to combine them into a paper, this is mosaic plag. Global plagiarism means presenting someone else’s work as yours while self-plag is about reusing paragraphs from your other essays.

Is plagiarism a crime?

Yes, it is. You’re facing the possibility of failing, being expelled, sued, or fired.

What exactly is plagiarism?

It is the borrowing or stealing of phrases & ideas and their inclusion into your work without proper citations.

Is self-plagiarism illegal?

Yes, it’s unacceptable both legally and in accordance with academic rules.

Online Plagiarism Checker For Students

Writing an academic paper can be challenging when you’re not sure if it’s original enough to pass a plagiarism check. Of course, students take information from various sites before writing their own text. Sometimes, it just so happens that certain parts are very similar to your resources, making your professor think that you’ve just copied work from somewhere. That’s why it’s crucial for any modern college or university student to ensure that their work has 100% original content to maintain academic integrity.

Luckily, a free plagiarism checker online can solve this issue quickly and easily. Many cheap essay writing services use a plagiarism checker for research paper.

Accurate Check for Plagiarism with Percentage

Many students wishing to produce original content aren’t quite sure how to get an exact percentage of plagiarised text in their work. This percentage is important since many universities have a certain limit of non-unique words you can have in your essay for it to be considered okay. If your plagiarism search doesn’t give you the exact percentage, you can’t be sure if your assignment will go through or not.

When using a free plagiarism tool, it’s essential to have this data provided to you. Only when you have it can you decide which parts to change and which ones to chuck out to achieve your desired results. Plagiarized content is a big issue in modern educational institutions, so getting reliable and trustworthy results is vital. This is the most essential requirement when you check plagiarism.

PapersOwl’s plagiarism detection tool gives you all the information you need to fix plagiarized content. Whether you’ve fallen victim to accidental plagiarism or have tried to make your life easier by copying some text from different sources, you’ll get an accurate percentage with our plagiarism checker online.

You’ll see the problematic parts with plagiarism detected highlighted, with links to where similar content exists. Our service with plagiarism detector will also give you the option to check my essay for plagiarism and then to hire a professional paper writer to fix your task quickly if you're busy with other things!

The Fastest Plagiarism Checker Online

Gaining insight into duplicate content only works if you get your results quickly. There are so many free plagiarism software online that promise to do the job for you. However, a lot of them are clunky, slow, and inaccurate. How can you produce original work without similarity detection you can trust?

PapersOwl stands out in this regard because it will detect plagiarism in seconds. This is a plagiarism scanner that’s able to perform a Swift Check to give you a uniqueness check right there and then. It also conducts a Deep Search, going through millions of sources on the internet to check for plagiarism. A document of about 1500 words takes only about 10 seconds to get processed! You get a clear plagiarism score of how much text is plagiarized and how much is original.

And on top of that, you get a handy Make It Unique button that’ll take you to an order page where you can ask our expert writers to rewrite your work and make it 100% unique.

All of this is done almost instantly, allowing students to continue do assignments without missing a beat. Not every plagiarism detection software works this quickly, making ours the best one you’ll ever use.

Plagiarism Checker Helps Boost Your Grade

A lot of students make the mistake of considering their papers automatically free from plagiarism. After all, they’ve written it themselves, so how could it be problematic? What they don’t realize is that it’s very easy to borrow some information mistakenly. Turning such a paper in can cause multiple problems, as your professor might think you haven’t done the work at all.

That is why you should always use a plagiarism scanner to test for plagiarized content in your college papers. Our online plagiarism checker for students is designed for this exact purpose. A simple, free plagiarism check could help you check plagiarism, fix any mistakes you see, and submit high-quality text that no one will question.

Our plagiarism detector has a lot going for it. It makes plagiarism detection easier than ever before.

All the matches are highlighted so you know what to change.

The plagiarism test will give you a uniqueness percentage too. This will help you figure out where you stand and how much time you need to adjust anything if required. So, using our copyright checker online free to check your writing is essential. This way, you’ll submit the task only when you’re sure it meets the level of uniqueness required by your school.

✍️ Rewriter Tool: An Easy Way to Avoid Plagiarism

Want to know when rewriting means plagiarizing?

It is easy.

When you use someone else’s intellectual property, pretending it’s your own, you plagiarize. When you reword a text that another person wrote without referencing the original, it is plagiarism.

Unfortunately, even if you unwillingly copy someone’s text, it is also punishable . The consequences range from lowered marks and reprimanding to expulsion from the educational institution or research community. Nobody likes plagiarizers. People perceive them as thieves.

Still, every researcher resorts to paraphrasing. What is the recipe for the balance between rewriting and plagiarism? The short answer is, always mention the original . There are more nuances, like retelling the text with your own words rather than using synonyms here and there. But whichever method or app you use, give credit to the author.

When you wish to use someone else’s words as a part of your writing, you insert a quote . In this case, you are supposed to enclose the phrase or sentence in quotation marks to signal that you are quoting. After that, include a citation with page number and author’s name.

When should you quote?

There is a general rule that if more than four words in a row match the source, you should enclose them in quotation marks.

But if the sentence or paragraph you wish to use is too long, it is better to paraphrase it. In such a case, quotation marks are unnecessary. Still, paraphrases also require citations at the end of the rewritten text and in the list of references. Make sure to modify the words and their order to avoid plagiarism.

You can consult the examples of quoting, rewriting, and plagiarism examples below. Compare them to find out the difference and never have problems using someone else’s text in your research article or essay.

Quoting: Example

The quote from a book by Oliver Sacks below contains quotation marks and a reference to the original according to APA citation style.

“The scientific study of the relationship between brain and mind began in 1861, when Broca, in France, found that specific difficulties in the expressive use of speech, aphasia, consistently followed damage to a particular portion of the left hemisphere of the brain. This opened the way to cerebral neurology, which made it possible, over the decades, to ‘map’ the human brain, ascribing specific powers — linguistic, intellectual, perceptual, etc. — to equally specific ‘centers’ in the brain. Toward the end of the century it became evident to more acute observers that this sort of mapping was too simple, that all mental performances had an intricate internal structure, and must have an equally complex physiological basis.” (Sacks, 1998, p. 5)

Rewriting: Example

The rewriting sample below contains all the essential features. All the grammatical structures of the sentences have been modified. Most words have been replaced with synonyms, and most importantly, it contains a reference to the original . You can use this example as a good one.

In “The Man Who Mistook His Wife for a Hat: And Other Clinical Tales,” Sacks (1998) describes the beginning of the research on brain and mind. In particular, Broca was the first to discover the relationship between aphasia and the damaged section of the left hemisphere. This finding started a breakthrough in cerebral neurology. In some decades, people described the brain’s structure with respect to its functions and the centers responsible for them. Later, researchers found that this approach overly simplified mental processes. On the contrary, the human brain has a complicated psychological structure, and its functioning is much more intricate.

Plagiarism: Example

This plagiarism sample does not change the sentence structure and frequently uses the same word order. Deleting the subordinate parts of sentences and changing some words with synonyms does not suffice for a good rewriting. Plagiarism checkers will recognize this passage as the original . But if your poor rewriting is revealed, you will be punished. Its main drawback is the absence of credit to the original.

The study of the brain and mind began in 1861 when Broca found that specific difficulties in the expressive use of speech usually followed damage to the left hemisphere of the brain. This gave impetus to the development of cerebral neurology, which made it possible to ‘map’ the human brain. Scientists ascribed specific powers — intellectual, linguistic, perceptual, etc. — to some particular areas in the brain. At the end of the century, it became evident that such mapping was too simple. Therefore, all mental activities had a complicated internal structure, and they must have an equally intricate physiological basis.

Personalized Writing Help When You Need it

Unintentional plagiarism, grammar mistakes, and uncited sources  can turn what you thought was a good paper into a poor one. When you’re writing a paper the last thing you want is for your message to get lost due to incorrect punctuation or confusing sentence structure. You know that the great ideas in your head would make for a standout paper, if only you could get them written clearly on the page. If this struggle sounds familiar, you’re not alone.

Great ideas may be an essential part of high-quality writing, but they’re not the only component. Excellent papers and essays clearly express strong ideas with good grammar, proper punctuation, spot-on spelling, and thorough, careful citations. While this may sound like a lot, your teachers and professors are grading you on your skills as both a writer and a researcher, which means your assignments will require an ethical and attentive approach. Luckily, there is no shortage of available tools to help you along your way.

You could use a plagiarism checker free, though, these tools often lack grammatical support. Given the high stakes and rigorous requirements, the aid of a plagiarism checker without the needed support of a grammar checker could mean the difference between an “A” paper and a “C” or even “D” paper.

Thankfully, the EasyBib Plus plagiarism tool provides all-in-one support to cover all your bases. Our premium essay checker is convenient, easy to use, and includes access to a grammar and spell checker, plus a plagiarism checker. With a single scan, you’ll receive personalized feedback to help identify potentially missing citations and help improve your sentence structure, punctuation, grammar, and more.

Not sure if that noun is spelled correctly, or if the preposition at the end of your sentence is grammatically correct? The EasyBib Plus plagiarism tool is your one-stop shop to help check plagiarism, get grammatical suggestions, correct spelling and punctuation errors, and help create polished papers you can be proud to turn in. And, we haven’t told you the best part yet: you can try our tool free and scan your work for grammar suggestions right now!

A Grammar Check for Peace of Mind

You know that grammar plays a significant role in your assignments. Not only does it factor into your overall grade, but without clear and precise language, your ideas can lose their impact or might even be misunderstood entirely. Still, with so many different parts of speech and rules to learn and apply, it’s not uncommon to get them mixed up and find yourself questioning your knowledge now and again:

Can you use an adverb to modify a noun? (No. You need an adjective for that.)

Well, can you use it to modify a pronoun ? (Still no.)

What do they modify, then? (Almost everything else. Fun, right?)

Ugh. (That was an interjection .)

Does this have to be so difficult? (Nope!)

Scanning your paper with the EasyBib Plus writing tool delivers more than the basic punctuation and spell check functions that come standard in word processing programs. You’ll receive immediate, targeted feedback that can help improve the sentence structure and style of your writing. Not only can this help ensure that you don’t lose points off your grade for grammatical errors such as mismatched verb tense, but it can also help to clarify your meaning and strengthen your arguments by eliminating confusing punctuation and run-on sentences that confuse readers.

Reviewing your work to correct errors and refine the flow of your writing is a critical part of the revision process for novices and novelists alike. Even the most conscientious of wordsmiths might make mistakes, such as using a conjunctive adverb in place of a coordinating conjunction or pairing a plural determiner with an uncountable word. They likely appreciate a subscription-based or free grammar check as much as a beginning writer. That’s why the EasyBib Plus writing tool is designed for all writers, from students who are still learning the fundamentals to published professionals who get paid by the word.

The EasyBib Plus writing tool provides quick, targeted feedback that you can use to help improve your writing immediately. Also, our free resource library is available 24/7, just like the rest of our tools, to help you brush up on the areas that challenge you the most (Conjunctive what? Uncountable who?) That means you can continue to sharpen your skills and improve your writing over time, which will help make finishing your next project easier.

Why is Grammar So Important, Anyway?

Why is grammar important? As long as others know what you mean, does it really matter if you use proper grammar? These are age-old questions, but the answers remain unchanged. Grammar is important for many reasons:

Communication:  Communication is about more than merely listening and talking. We communicate in myriad ways: with our voices, our mannerisms, our facial expressions, our actions, and frequently, our written words. Written communication is just as important as all the other ways we broadcast our thoughts and feelings. Unlike our other communication methods, though, written communication leaves a record. While most of us relax our style when talking to or texting friends, the fact remains that more formal venues require a more formal tone. Proper spelling, grammar, and punctuation are a necessary element of professional and academic writing, so running your work through a spelling and grammar check before you submit it is an absolute must.

Clarity:  Expressing your thoughts, ideas, and opinions is an uphill battle when you communicate them with less-than-stellar punctuation, spelling, and grammar. A missing or misplaced comma, for example, can entirely change your meaning:

• Call me Ishmael = My name is Ishmael.
• Call me, Ishmael = I want Ishmael to call me.

Spelling errors can result in similarly muddled meaning:

• Her shoes perfectly complemented her dress. = Her shoes and dress go well together.
• Her shoes perfectly complimented her dress. = Her shoes can both speak and engage in flattery.

Grammar deficiencies such as a dangling modifier yield similarly confusing results:

• I saw the girl’s purple backpack in the library. = The purple backpack belonging to the girl is in the library; I saw it.
• I saw the purple girl’s backpack in the library. = You know the girl who mysteriously turned purple? I saw her backpack in the library. This week has not been easy on her.

Credibility: Establishing your credibility is critical whether you’re writing for school or business. Proving that you can reliably communicate using proper grammar is essential to establishing and maintaining the trust of your teachers, professors, readers, customers, and colleagues.

What Happens After I Upload My Paper?

Once you upload a paper, the EasyBib Plus grammar checker scans your text and highlights grammar issues within your document so you can see it in context. For users running a grammar check and spell check using the grammar check free tool, up to the first 5 issues are shown. For subscription subscribers, all of the areas that require your review will be highlighted once the scan is complete.

No matter which version of the tool you’re using, your feedback will include detailed explanations so you can understand why the text was flagged. Other highlighted areas will include examples of how the issues can be fixed. Some will include a detailed explanation as to why the issue was flagged. This personalized feedback allows you to make an educated decision about whether to edit your text or dismiss the suggestion, so you’re always in control of your final draft.

Subscription users also have the plagiarism checker at their disposal when scanning their papers for style and grammar suggestions. Just as with our other writing tools, when you use the tool to check plagiarism, changes are never made without your review, so you are always in the driver’s seat. You can review each highlighted area as well as the sources of matching text and will always be given a choice to either accept or ignore both citation and grammar suggestions.

Whether you are a student or a professional, the EasyBib Plus tools are powerful allies that can help you improve your paper, establish credibility as a writer, and maintain an ethical writing process.

Check for Unintentional Plagiarism

Persistent use of the best grammar checker and spell checker you can find will help to shape up the style and substance of your composition. However, to ensure the integrity of your work and root out unintentional instances of academic dishonesty, you’ll also need to incorporate a subscription-based or free plagiarism checker for students.

The ability to scan your paper and check plagiarism and grammar before submitting your work is an invaluable tool for students. It’s so valuable, in fact, that students are not the only ones who consistently use this type of software.

Many teachers and professors use a service to ensure that student papers are original and include properly formatted and sourced citations for all reference materials. For some, this may be a consistent element of their grading process, while others may utilize one only when they feel there is a reason to do so.

What Exactly Does a Plagiarism Checker Do?

If you’ve used an online plagiarism checker before, you may be familiar with the process that these tools employ. For those who have never used one, it can be helpful to understand how these tools work and what you should expect as a result of using one.

The most basic free tools will scan your paper and provide you with a percentage that indicates how much of your work is original. This feature can be useful to a point, as some instructors and institutions set a percentage for the amount of similar text that is considered acceptable. This policy does not mean that they are lenient about academic dishonesty but, instead, that they recognize that similar or even matching word choice is not always an indicator of copying.

However, some schools do not tolerate any form of incremental plagiarism, period. In these institutions, “check paper for plagiarism” is likely a standard action when grading all papers.

With a free plagiarism checker, the percentage of word-for-word plagiarism in your text may be the only feedback you receive. Moreover, some of these providers may wade in unethical waters, and offer essay writing services in conjunction with their checking services. This is why many students and teachers prefer subscription-based checkers that focus on integrity, such as the EasyBib writing tools.

With our premium tools, you get more than just supporting proof that your paper is original and in your own words. Your writing is scanned for potentially matching text and areas that needs your attention is highlighted. We’ll provide you with the source of the matching text so you can review it and decide how to proceed. If you agree that a citation is needed, our citation tools and resources will provide you with the information you need to help format and insert the new sources in your text as well as your works cited page.

How Does the EasyBib Plus Online Plagiarism Checker Work?

The EasyBib Plus writing tool provides an all-in-one spell check, grammar review, and plagiarism checker that not only helps you with the paper you’re writing now but enables you to gain new knowledge and improve your writing for the future, too.

Our essay checker searches online for phrases, sentences, or passages that are similar to those in your paper. If it returns matching text, this may indicate that you have passages that are missing citations.

Just as with many checkers, our tool will tell you how many instances of matching text it finds in your paper. Our plagiarism tool is designed to do more than most free tools, however.

When a portion of your paper is flagged for review, we provide you with the source that it matches. As with our online spell check tool, you have the power to review each area and choose how to proceed. If you decide to cite the flagged text, you can review the suggested source and access our citation tools to help create a proper citation and start building a bibliography for your paper. Or, you may determine that no citation is needed, in which case it’s simple to dismiss the suggestion and continue to the next section.

If you’re unsure about how to proceed, our library of resources can help you learn more and make an educated decision. In this way, you gain more than just the ability to correct your work; over time, you can learn how to avoid plagiarism altogether.

Reasons Your Teacher May Run Your Paper Through a Plagiarism Detector

As stated previously, your teachers and professors grade papers with a fixed process that includes “check paper for plagiarism” as a standard, across-the-board action. Others may check for plagiarism only when they feel there is cause to do so. There are a few red flags that may stand out to them while reviewing a paper that would lead to their running a plagiarism check, including:

Style/Voice:  Most teachers are familiar with the style and voice that you use in your writing. While most will hope that the feedback they provide when grading your work will help you to improve problem areas over time, a paper or essay that has a dramatically different style or voice than the work you’ve previously submitted can be a red flag.

Inconsistency:  Changes in the font, font size, formality, formatting, and more may indicate that portions of a paper have been copied and pasted. If these inconsistent passages are not presented as quotations or don’t include citations, this may further indicate to your teacher that there’s plagiarism in the paper.

Old References:  Part of a well-researched paper is verifying the legitimacy and relevance of your sources. While some older references may be acceptable depending on the topic, if all of your sources are outdated, it may lead your teacher to believe that you’ve recycled your own work or someone else’s.

What is Plagiarism?

If you’re looking for a free online plagiarism checker , you’re already aware that it’s not something you want to be found in your papers. However, you may still be wondering: what does plagiarism mean? It’s a reasonable question and one that merits exploring. After all, some of the actions and circumstances that fall within the plagiarism definition come as a surprise to those who only learn that they’ve committed them after it’s too late.

So what is plagiarism? To define plagiarism in the most basic sense, you might say that it is taking someone else’s ideas and words and passing them off as your own.

If your goal is avoiding plagiarism entirely, you’ll need to go beyond the basics to thoroughly define plagiarism, recognize it, and keep clear of it. Some examples of plagiarism that students find surprising include forgotten citations, poor paraphrasing, and re-submitting your own work in whole or in part for more than one assignment. This useful article provides more help in recognizing and understanding the different forms that academic dishonesty can take.

Of course, using your own words and ideas does not count as plagiarism, nor does using common knowledge . Basically, common knowledge is information that is well known by the average person. Examples of common knowledge:

• there are 12 months in a year
• the freezing point of Celsius is zero degrees
• Socrates was a Greek philosopher

So should you only include your original thoughts and common knowledge in your papers? Of course not! Research-based assignments are meant to demonstrate your skills as a researcher, after all, as well as your ability to build upon the work of others to formulate new ideas. To avoid accidentally committing an act that falls within the plagiarism definition when you’re using another person’s words or ideas, though, you need to give them proper credit. This means you’ll need to clearly identify direct quotations or properly paraphrase them when including them in your paper.

Regardless of your approach, you’ll also need to cite your sources according to the style your professor specifies. Generally, you will use MLA format for the arts and humanities and APA format for the sciences, but it’s always best to check with your instructor when you’re unsure.

If you know what style to use but still aren’t sure how to create your citations, don’t fret! Our library of resources includes free guides to help you learn about various styles so you can properly structure and place them. And our premium tools not only help you check grammar, spelling, and originality in your papers, but subscribers also enjoy access to our citation creation tools!

What are the Different Types of Plagiarism?

In addition to the question “what is plagiarism,” you may also be wondering, “why do students plagiarize?” While some students do intentionally plagiarize because they believe they can pass off someone else’s work as their own to avoid spending time on their assignments, many others do so accidentally. They may not understand how broad the plagiarism definition is or they haven’t learned how to research and cite their sources properly. That is why it is vital to recognize plagiarism in all of its forms if you wish to ensure the integrity of your work.

Examples of plagiarism & How to prevent it

Direct plagiarism:

Intentionally copying another person’s work without including a citation that gives credit to the source. When most students are asked to identify potential plagiarism examples and behaviors, this direct and deliberate act is what they think of first.

• Prevention: If you use an idea or quote from another source, cite it in the text. Make it clear that it was not your own words. 

Incremental plagiarism:

Copying parts of another person’s work, such as phrases, sentences, or paragraphs without crediting the source. When deciding which tools to use to check a paper for plagiarism , instructors often seek out those that will identify incremental forms as well as instances of direct copying and similar phrasing.

• Prevention : Decide to either directly quote the phrases or sentences you want to use, or write a good paraphrase. In both cases, be sure to add a citation. Using a plagiarism checker could also help you identify problematic passages.

Self-plagiarism:

Academic self-plagiarism occurs when a student submits the same paper or parts of a paper for more than one assignment. When your instructors are grading your papers, they’re assessing your research and writing skills in the present. When you submit work that you completed in the past, they are both unable to evaluate your current skills and unaware that you haven’t completed the assignment.

• Prevention: Write a new paper for each assignment you’re assigned. If you feel strongly that your past work could enhance your new paper, speak to your instructor and ask for permission first.

Misleading citations:

Including a citation for a quote or idea that misrepresents the source material. This can occur if a student does not understand the reference they are citing; if a student includes a citation for a disreputable source; or the source material simply does not align with the idea or argument that the student has attributed to it.

• Prevention: Carefully review your assignment to understand it. As you research, take the time to evaluate each source notes . Remember, it’s better to have quality citations over an abundance of citations.

Invented sources:

If a reference in a student’s bibliography is found not to exist, it is considered an invented source. This may occur if a student couldn’t find a reputable source to back their argument, or if they needed to include additional references to meet the requirements of the assignment and chose to take an unethical shortcut rather than completing the required amount of research. No matter the reason, this behavior ultimately hurts them in the long run. Not only will they fail to gain the experience they need to conduct research in the future properly, but they’ll also experience significant consequences if they’re caught.

• Prevention: Set aside time to do proper research so you can find enough sources. Start creating a list of sources as you’re researching and take good notes. This will help you keep track of your sources so none are forgotten. If you do end up forgetting where a quote came from, a paper checker could help you pinpoint the original source. 

Patchwriting/Spinning:

Patchwriting is often confused with paraphrasing, but there’s a significant difference. When you paraphrase, you demonstrate that you understand the topic well enough to restate it in your own words. When you patchwrite or spin, it is more akin to a word-swapping game; there’s no need to understand the subject, merely to have access to a thesaurus so you can substitute enough synonyms to mask the source material. This can be intentional, but it may also be a result of having a poor understanding of how to paraphrase.

• Prevention: Using your own words, write down the key points of the phrase or idea, and put them together in a sentence. Be sure to include a citation as well. 

A good way to test if you’re patchwriting or paraphrasing is to remove your sources from view. If you can write about what you’ve read without looking at the source material, you likely understand it well enough to paraphrase it. If you have to review the source material with each new sentence or consult a thesaurus while writing about it (except when you’re adding direct quotations), you may be spinning your sources instead of paraphrasing them.

Academic Integrity Policies and Statements

If you’re still uncertain about what counts as plagiarism, look for your school’s/ organization’s policies on academic integrity and plagiarism. The policies of academic institutions usually cover what is considered plagiarism, the consequences of committing it, and how to avoid it. One great example is Purdue University’s Academic Integrity statement .

What are the Consequences of Plagiarism?

No matter the setting, plagiarism is not taken lightly, and the consequences can be significant. For a good reason, too! Whether in an academic or professional setting, the plagiarism consequences reflect the seriousness of the act, which is ultimately a form of theft that hurts everyone involved.

Just as with the theft of a tangible object, there can be legal punishments for plagiarism. It is, after all, a form of copyright infringement in many instances. A quick search for plagiarism articles will reveal that professional instances of intellectual theft have resulted in civil lawsuits and can even be criminally prosecuted under rare circumstances. In addition to the possible legal consequences, professionals may lose their jobs or have to start over in a new field after their acts of fraud are uncovered.

As a student, you’re likely to wonder what happens if you plagiarize in college or high school. While there will almost always be consequences for this behavior, there is no one-size-fits-all plagiarism sentence. Depending on the circumstances, academic dishonesty could result in outcomes such as:

• You might get a zero for the assignment in which the infringement occurred.
• You may receive a failing grade for the class. If it is a required course, this could leave you without enough credits to move on to the next level until you can repeat it and, in some instances, postpone graduation.
• You may be expelled from your school or university.

The academic dishonesty may be noted on your transcript, which can lead to you not getting into your preferred college, graduate school, or Ph.D. program in the future.

Nobody wants to be known as a fraud or to have a reputation for dishonesty follow them through their career. And, given the consequences that can extend beyond just their reputation, it’s no wonder that professional and academic writers who wish to avoid them take the time to understand the complete definition of plagiarism and run their work through a plagiarism checker before sending it out into the world.

Even the vigilant can fall prey to inferior tools, unfortunately. Before selecting a plagiarism checker, you should understand how they work and what they can (and cannot) detect.

How We Check for Plagiarism

When exploring how to check for plagiarism, most students and professionals conclude that including a checking tool in their revision process is not only helpful but necessary. When you consider the Herculean task of checking each line of your paper against the text of each of your resources, the benefits of a checker are clear. Moreover, this manual approach would only alert you to matching text in the sources you’re aware of, after all, and leaves the sources you haven’t reviewed untouched.

But, hang on. Why would sources you haven’t reviewed factor into your review? The answer to this lies in the plagiarism definition you learned above. What is plagiarism? It’s presenting someone else’s work or ideas as your own, intentionally or otherwise. It is not uncommon to uncover an idea while you’re researching a topic and later misremember it as your own. This might even occur years after you originally came across it.

You might wonder: how can plagiarism be avoided if you have to account for the source of every thought you include in your work? A few exceptions minimize the scope of this. Common knowledge about your topic does not need to be supported by a citation, nor does knowledge that you gained through your personal experience. Using a subscription-based or free plagiarism checker will help you locate any passages that may fall into these categories so you can review them and decide for yourself whether a citation is needed.

EasyBib Plus writing tools provide easy, convenient, and reliable support to help you find potentially missed citations and can help you improve your paper into a high-quality paper with integrity. Simply upload your paper, select the checker, then sit back and relax as the site scans your document. In mere moments, we’ll search the web for passages of similar text and highlight duplicate content for your review.

Regardless of the tools you use to help you revise and polish your work, it’s ultimately your responsibility to ensure that you’re writing and submitting ethical work. That’s why our tools go beyond the basics and require your participation. The tool never automatically makes changes to your paper, but only flags sections that may need your attention and provides you with the matching source so you can to make an educated decision.

If you find that a citation is needed, our citation tools can help you create properly formatted citations and develop a complete bibliography. And, if you review the passage and determine that the match is coincidental, you can dismiss the alert and move on to the next.

Seamless Citation Creation

Professional writers and students alike can find creating citations incredibly confusing. Nevertheless, they are an integral part of a well-written and researched paper and a requirement in almost all academic settings. But, have you ever wondered why they are so important? Citations really do have a purpose—other than driving us crazy— that make it necessary always to cite our sources.

We cite our sources for a few important reasons:

We need to give credit where credit is due. When you use a quote from someone else’s work, you need to give credit for using their words and ideas. Research is often based on the works and ideas of others. However, to include the words and ideas of another without giving them proper credit is to plagiarize, even if the act was unintentional.

In addition, showing that you’ve done proper research by including in text & parenthetical citations and a comprehensive list of sources to back up your arguments gives your work a layer of credibility that can help you earn the trust of your reader or teacher.

Readers can find the sources you used.  When you’re writing high school or undergraduate papers, your only readers may be your instructors and peers. However, including citations at every level of writing helps to ensure that anyone who reads your work can access your sources to check their accuracy, learn more about your topic, and further their own research.

Sources can take your research and learning to the next level, too. When you are conducting research on a topic, checking the works cited or annotated bibliographies prepared by your sources can lead you down new avenues in your research to further develop your ideas and help you write your papers.

Correctly utilizing citations gives strength to your thoughts and opinions. Understanding the value of citations does not, unfortunately, make them any easier to create. We know how confusing it can be, but don’t throw in the towel on learning how to cite websites in MLA , create your APA citation website references, or format your works cited —this is where we come in!

While a free online plagiarism detector may tell you how much of your work is unoriginal and may even identify the passages that meet their plagiarize definition, a premium EasyBib Plus plagiarism checker account also gives you access to our powerful citation resources and generator so you can:

Scan your papers with the plagiarism tool to check for plagiarism-free work before you submit.
