Common questions about plagiarism, more tools and resources for avoiding plagiarism, frequently asked questions about plagiarism.

It’s easy to understand why you shouldn’t buy essays, but students often struggle with the details of quoting , paraphrasing , and citing sources . Below, we address some questions and misconceptions students often have about plagiarism.

I need to quote and paraphrase a lot. Won’t my paper be full of distracting citations?

It’s true that some papers do feature a lot of citations. There are ways to reduce clutter by citing more efficiently, such as:

• Combining multiple citations into one set of parentheses (usually separated by semicolons )
• Not repeating the full citation when you cite the same source multiple times in a row
• Using “ ibid. ” to indicate a repeated citation (in certain styles)
• Omitting citations for information that is common knowledge

Do I need to cite a certain number of sources? Can citing too much be a bad thing?

There’s no fixed number of sources you should cite. Your use of sources should be based on strengthening your argument, not meeting a quota. A high number of citations isn’t inherently a good or bad thing. Some types of academic text (e.g., a literature review ) are more likely to cite a lot of sources than others.

When you do think you’ve cited too much, it’s worth considering whether you need all the information you’ve included. All information should directly contribute to your argument, not just be tangentially related.

One thing you should avoid is quoting too much. If large portions of your text consist of someone else’s words, it distracts from your own arguments. It’s usually better to paraphrase unless you’re specifically analyzing the language of the source (e.g., in literary analysis ).

Is it better to just avoid using sources so I don’t risk accidental plagiarism?

No, using sources is an essential part of academic writing . Academic research is an ongoing conversation between researchers. Drawing on other sources, and positioning your own ideas in relation to them, is not optional.

But it’s understandable to be concerned about plagiarism. If you’re worried about the possibility of accidental plagiarism, make sure to:

• Quote and paraphrase sources correctly
• Manage and cite your sources using a citation generator
• Use a plagiarism checker before submitting your work to detect any problems
• Use generative AI tools responsibly (outputs may be detected by an AI detector )

Is paraphrasing a kind of plagiarism?

No, paraphrasing is just a way of incorporating information from a source into your text by putting it into your own words. As long as you cite the source correctly, paraphrasing is the best way to incorporate information in most cases.

However, paraphrasing can be considered plagiarism if you:

• Don’t cite the source of the information, or cite it incorrectly
• Phrase the information in a way that’s too close to the original (e.g., just swapping out a couple of words instead of reformulating the sentence)

Scribbr offers a variety of tools and services designed to help you with citations and plagiarism checking, including the best plagiarism checker available.

The consequences of plagiarism vary depending on the type of plagiarism and the context in which it occurs. For example, submitting a whole paper by someone else will have the most severe consequences, while accidental citation errors are considered less serious.

If you’re a student, then you might fail the course, be suspended or expelled, or be obligated to attend a workshop on plagiarism. It depends on whether it’s your first offense or you’ve done it before.

As an academic or professional, plagiarizing seriously damages your reputation. You might also lose your research funding or your job, and you could even face legal consequences for copyright infringement.

Paraphrasing without crediting the original author is a form of plagiarism , because you’re presenting someone else’s ideas as if they were your own.

However, paraphrasing is not plagiarism if you correctly cite the source . This means including an in-text citation and a full reference, formatted according to your required citation style .

As well as citing, make sure that any paraphrased text is completely rewritten in your own words.

Accidental plagiarism is one of the most common examples of plagiarism . Perhaps you forgot to cite a source, or paraphrased something a bit too closely. Maybe you can’t remember where you got an idea from, and aren’t totally sure if it’s original or not.

These all count as plagiarism, even though you didn’t do it on purpose. When in doubt, make sure you’re citing your sources . Also consider running your work through a plagiarism checker tool prior to submission, which work by using advanced database software to scan for matches between your text and existing texts.

Scribbr’s Plagiarism Checker takes less than 10 minutes and can help you turn in your paper with confidence.

Plagiarism can be detected by your professor or readers if the tone, formatting, or style of your text is different in different parts of your paper, or if they’re familiar with the plagiarized source.

Many universities also use plagiarism detection software like Turnitin’s, which compares your text to a large database of other sources, flagging any similarities that come up.

It can be easier than you think to commit plagiarism by accident. Consider using a plagiarism checker prior to submitting your paper to ensure you haven’t missed any citations.

The accuracy depends on the plagiarism checker you use. Per our in-depth research , Scribbr is the most accurate plagiarism checker. Many free plagiarism checkers fail to detect all plagiarism or falsely flag text as plagiarism.

Plagiarism checkers work by using advanced database software to scan for matches between your text and existing texts. Their accuracy is determined by two factors: the algorithm (which recognizes the plagiarism) and the size of the database (with which your document is compared).

What is plagiarism and how to avoid it?

Writing a manuscript is an art. Any clinician or an academician, has a hidden desire to publish his/her work in an indexed journal. Writing has been made mandatory for promotions in certain departments, so the clinicians are more inclined to publish. Often, we note that we (Indian Journal of Orthopaedics) receive more articles from China, Turkey, and South Korea (abroad) instead of from our own country though the journal is an official publication of Indian Orthopaedic Association. Therefore, we have decided to encourage more and more publications, especially from our own country. For that reason, we have decided to educate our members by publishing an editorial on “How to write a paper?,” which is likely to be published soon. In one of our last editorials, we discussed indexing. In this issue, we will be discussing the plagiarism. In forthcoming issues, we are planning to discuss “Ethics in publication,” How to write Introduction, Materials and Methods, Results, Discussion, Referencing, Title, Abstract, and Keywords, and then how to write case report which is acceptable. The editorial team tries to help out our readers, so that their hidden instinct of writing their own work could be made true.

D EFINITION OF P LAGIARISM

Plagiarism is derived from Latin word “ plagiarius ” which means “kidnapper,” who abducts the child. 1 The word plagiarism entered the Oxford English dictionary in 1621. Plagiarism has been defined by the Encyclopedia Britannica as “the act of taking the writings of another person and passing them off as ones own.” 2 It is an act of forgery, piracy, and fraud and is stated to be a serious crime of academia. 3 It is also a violation of copyright laws. Honesty in scientific practice and in publication is necessary. The World Association of Medical Editors 4 (WAME) defines plagiarism as “… the use of others’ published and unpublished ideas or words (or other intellectual property) without attribution or permission and presenting them as new and original rather than derived from an existing source.”

In 1999, the Committee on Publication Ethics (COPE) 5 , 6 defined plagiarism as “Plagiarism ranges from the unreferenced use of others’ published and unpublished ideas including research grant applications to submission under new authorship of a complex paper, sometimes in a different language. It may occur at any stage of planning, research, writing or publication; it applies to print and electronic versions.”

F ORMS OF P LAGIARISM

• Verbatim plagiarism: When one submits someone else's words verbatim in his/her own name without even acknowledging him publically. Copy and paste from a published article without referencing is a common form of verbatim plagiarism. Most commonly, it is seen in introduction and discussion part of manuscript 2 , 7
• Mosaic plagiarism: In this type of plagiarism each word is not copied but it involves mixing ones own words in someone else's ideas and opinions. This is copying and pasting in patchy manner 2
• Paraphrasing: If one rewrites any part/paragraph of manuscript in his/her own words it is called paraphrasing. Paraphrasing is a restatement in your own words, of someone else's ideas. Changing a few words of the original sentences does not make it your writing. Just changing words cannot make it the property of borrower; hence, this should be properly referenced. If it is not referenced, it will amount to plagiarism
• Duplicate publication: When an author submits identical or almost identical manuscript (same data, results, and discussion) to two different journals, it is considered as duplicate (redundant) publication. 9 As per COPE guidelines, this is an offense and editor can take an action as per the COPE flowchart
• Augmented publication: If the author adds additional data to his/her previously published work and changes title, modifies aim of the study, and recalculates results, it amounts to augmented publication. Plagiarism detection software usually do not pick it because it is not same by verbatim. This self plagiarism is as such technical plagiarism and is not considered with same strictness as plagiarism. The editor may consider it for publication in the following three situations: If author refers to his/her previous work; if ’methods’ cannot be written in any other form; and if author clearly states that new manuscript contains data from previous publication 10
• Segmented publication: Also called “Salami-Sliced” publication. In this case, two or more papers are derived from the same experimental/research/original work. Salami-sliced papers are difficult to detect and usually are pointed out by reviewers or readers. The decision regarding such manuscript is again on editor's shoulder. The author must be asked to refer to his/her previously published work and explain reasonably the connection of the segmented paper to his/her previously published work
• Text recycling: If the author uses large portions of his/her own already published text in his/her new manuscript, it is called text recycling. It can be detected by plagiarism software. It can be handled as per the COPE guidelines.
• Cyber plagiarism: “Copying or downloading in part or in their entirety articles or research papers and ideas from the internet and not giving proper attribution is unethical and falls in the range of cyber plagiarism” 2
• Image plagiarism: Using an image or video without receiving proper permission or providing appropriate citation is plagiarism. 7 “Images can be tampered on support findings, promote a specific technique over another to strengthen the correctness of poorly visualized findings, remove the defects of an image and to misrepresent an image from what it really is”? 11

H OW TO D ETECT P LAGIARISM ?

It is generally difficult to detect plagiarism, but information technology has made available few websites which can detect/catch plagiarism. Few of them are www.ithentical.com , www.turnitin.com , www.plagiarism.org , etc. 12

Besides this, learned and watchful reviewers and readers can detect it due to his/her familiarity with published material in his/her area of interest.

H OW TO A VOID P LAGIARISM ?

Practice the ethical writing honestly. Keep honesty in all scientific writings. Crediting all the original sources. When you fail to cite your sources or when you cite them inadequately, you commit plagiarism, an offense that is taken extremely seriously in academic world and is a misconduct. Some simple dos and don’ts 5 are outlined in Table 1 .

Dos and don’ts of plagiarism

In the following situation, permission is required to use published work from publisher to avoid plagiarism. 8

• Directly quoting significant portion of a published work. How much text may be used without approaching publisher for permission is not specified. The best approach is whenever in doubt, ask for permission
• Reproducing a table
• Reproducing a figure/image.

H OW TO D EAL W ITH P LAGIARISM

Plagiarism is considered academic dishonesty and breach of ethics. Plagiarism is not in itself a crime but can constitute copyright infringement. 7 In academia, it is a serious ethical offense. Plagiarism is not punished by law but rather by institutions. Professional associations, educational institutions, and publishing companies can pose penalties, suspensions, and even expulsions of authors. 7

As per the COPE guidelines, “If editors suspect misconduct by authors, reviewer's editorial staff or other editors then they have a duty to take action. This duty extends to both published and unpublished papers. Editors first see a response from those accused. If the editors are not satisfied with the response, they should ask the employers of the authors, reviewers, or editors or some other appropriate body to investigate and take appropriate action.” 6

If the editor is satisfied that the act of plagiarism has taken place, minimum he should do is “reject” the manuscript if it is in different stage of editorial process and “retract” if it is already published.

To conclude, we must increase awareness about plagiarism and ethical issues among our scientists and authors. We must be honest in our work and should not violate copyright law. There should be serious steps against authors, which should bring disrespect to author and even loss of his academic position.

We will end it by quote of Albert Einstein “Many people say that it is the intellect which makes a great scientist, they are wrong, it is the character.”
