Writing Research Papers

• Writing a Literature Review

When writing a research paper on a specific topic, you will often need to include an overview of any prior research that has been conducted on that topic.  For example, if your research paper is describing an experiment on fear conditioning, then you will probably need to provide an overview of prior research on fear conditioning.  That overview is typically known as a literature review.  

Please note that a full-length literature review article may be suitable for fulfilling the requirements for the Psychology B.S. Degree Research Paper .  For further details, please check with your faculty advisor.

Different Types of Literature Reviews

Literature reviews come in many forms.  They can be part of a research paper, for example as part of the Introduction section.  They can be one chapter of a doctoral dissertation.  Literature reviews can also “stand alone” as separate articles by themselves.  For instance, some journals such as Annual Review of Psychology , Psychological Bulletin , and others typically publish full-length review articles.  Similarly, in courses at UCSD, you may be asked to write a research paper that is itself a literature review (such as, with an instructor’s permission, in fulfillment of the B.S. Degree Research Paper requirement). Alternatively, you may be expected to include a literature review as part of a larger research paper (such as part of an Honors Thesis). 

Literature reviews can be written using a variety of different styles.  These may differ in the way prior research is reviewed as well as the way in which the literature review is organized.  Examples of stylistic variations in literature reviews include: 

• Summarization of prior work vs. critical evaluation. In some cases, prior research is simply described and summarized; in other cases, the writer compares, contrasts, and may even critique prior research (for example, discusses their strengths and weaknesses).
• Chronological vs. categorical and other types of organization. In some cases, the literature review begins with the oldest research and advances until it concludes with the latest research.  In other cases, research is discussed by category (such as in groupings of closely related studies) without regard for chronological order.  In yet other cases, research is discussed in terms of opposing views (such as when different research studies or researchers disagree with one another).

Overall, all literature reviews, whether they are written as a part of a larger work or as separate articles unto themselves, have a common feature: they do not present new research; rather, they provide an overview of prior research on a specific topic . 

How to Write a Literature Review

When writing a literature review, it can be helpful to rely on the following steps.  Please note that these procedures are not necessarily only for writing a literature review that becomes part of a larger article; they can also be used for writing a full-length article that is itself a literature review (although such reviews are typically more detailed and exhaustive; for more information please refer to the Further Resources section of this page).

Steps for Writing a Literature Review

1. Identify and define the topic that you will be reviewing.

The topic, which is commonly a research question (or problem) of some kind, needs to be identified and defined as clearly as possible.  You need to have an idea of what you will be reviewing in order to effectively search for references and to write a coherent summary of the research on it.  At this stage it can be helpful to write down a description of the research question, area, or topic that you will be reviewing, as well as to identify any keywords that you will be using to search for relevant research.

2. Conduct a literature search.

Use a range of keywords to search databases such as PsycINFO and any others that may contain relevant articles.  You should focus on peer-reviewed, scholarly articles.  Published books may also be helpful, but keep in mind that peer-reviewed articles are widely considered to be the “gold standard” of scientific research.  Read through titles and abstracts, select and obtain articles (that is, download, copy, or print them out), and save your searches as needed.  For more information about this step, please see the Using Databases and Finding Scholarly References section of this website.

3. Read through the research that you have found and take notes.

Absorb as much information as you can.  Read through the articles and books that you have found, and as you do, take notes.  The notes should include anything that will be helpful in advancing your own thinking about the topic and in helping you write the literature review (such as key points, ideas, or even page numbers that index key information).  Some references may turn out to be more helpful than others; you may notice patterns or striking contrasts between different sources ; and some sources may refer to yet other sources of potential interest.  This is often the most time-consuming part of the review process.  However, it is also where you get to learn about the topic in great detail.  For more details about taking notes, please see the “Reading Sources and Taking Notes” section of the Finding Scholarly References page of this website.

4. Organize your notes and thoughts; create an outline.

At this stage, you are close to writing the review itself.  However, it is often helpful to first reflect on all the reading that you have done.  What patterns stand out?  Do the different sources converge on a consensus?  Or not?  What unresolved questions still remain?  You should look over your notes (it may also be helpful to reorganize them), and as you do, to think about how you will present this research in your literature review.  Are you going to summarize or critically evaluate?  Are you going to use a chronological or other type of organizational structure?  It can also be helpful to create an outline of how your literature review will be structured.

5. Write the literature review itself and edit and revise as needed.

The final stage involves writing.  When writing, keep in mind that literature reviews are generally characterized by a summary style in which prior research is described sufficiently to explain critical findings but does not include a high level of detail (if readers want to learn about all the specific details of a study, then they can look up the references that you cite and read the original articles themselves).  However, the degree of emphasis that is given to individual studies may vary (more or less detail may be warranted depending on how critical or unique a given study was).   After you have written a first draft, you should read it carefully and then edit and revise as needed.  You may need to repeat this process more than once.  It may be helpful to have another person read through your draft(s) and provide feedback.

6. Incorporate the literature review into your research paper draft.

After the literature review is complete, you should incorporate it into your research paper (if you are writing the review as one component of a larger paper).  Depending on the stage at which your paper is at, this may involve merging your literature review into a partially complete Introduction section, writing the rest of the paper around the literature review, or other processes.

Further Tips for Writing a Literature Review

Full-length literature reviews

• Many full-length literature review articles use a three-part structure: Introduction (where the topic is identified and any trends or major problems in the literature are introduced), Body (where the studies that comprise the literature on that topic are discussed), and Discussion or Conclusion (where major patterns and points are discussed and the general state of what is known about the topic is summarized)

Literature reviews as part of a larger paper

• An “express method” of writing a literature review for a research paper is as follows: first, write a one paragraph description of each article that you read. Second, choose how you will order all the paragraphs and combine them in one document.  Third, add transitions between the paragraphs, as well as an introductory and concluding paragraph. 1
• A literature review that is part of a larger research paper typically does not have to be exhaustive. Rather, it should contain most or all of the significant studies about a research topic but not tangential or loosely related ones. 2   Generally, literature reviews should be sufficient for the reader to understand the major issues and key findings about a research topic.  You may however need to confer with your instructor or editor to determine how comprehensive you need to be.

Benefits of Literature Reviews

By summarizing prior research on a topic, literature reviews have multiple benefits.  These include:

• Literature reviews help readers understand what is known about a topic without having to find and read through multiple sources.
• Literature reviews help “set the stage” for later reading about new research on a given topic (such as if they are placed in the Introduction of a larger research paper). In other words, they provide helpful background and context.
• Literature reviews can also help the writer learn about a given topic while in the process of preparing the review itself. In the act of research and writing the literature review, the writer gains expertise on the topic .

• Avoiding Plagiarism
• Google Scholar

A  literature review  is a compilation of the works published in a particular field of study or line of research, usually over a specific period of time, in the form of an in-depth, critical bibliographic essay or annotated list in which attention is drawn to the most significant works.

• Summarizes and analyzes previous research relevant to a topic
• Includes scholarly books and articles published in academic journals
• Can be an specific scholarly paper or a section in a research paper

The objective of a Literature Review is to find previous published scholarly works relevant to an specific topic

• Help gather ideas or information
• Keep up to date in current trends and findings
• Help develop new questions

A literature review is important because it:

• Explains the background of research on a topic
• Demonstrates why a topic is significant to a subject area
• Helps focus your own research questions or problems
• Discovers relationships between research studies/ideas
• Suggests unexplored ideas or populations
• Identifies major themes, concepts, and researchers on a topic
• Tests assumptions; may help counter preconceived ideas and remove unconscious bias
• Identifies critical gaps, points of disagreement, or potentially flawed methodology or theoretical approaches

1. Choose a topic. Define your research question. 

Your literature review should be guided by a central research question. It represents background and research developments related to a specific research question, interpreted, and analyzed by you in a synthesized way. 

• Make sure your research question is not too broad or too narrow.
• Write down terms that are related to your question for they will be useful for searches later. 

2. Decide on the scope of your review. 

How many studies do you need to look at? How comprehensive should it be? How many years should it cover? 

• This may depend on your assignment.
• Consider these things when planning your time for research. 

3. Select the databases you will use to conduct your searches. 

• By Research Guide 

4. Conduct your searches and find the literature. 

• Review the abstracts carefully - this will save you time!
• Many databases will have a search history tab for you to return to for later.
• Use bibliographies and references of research studies to locate others.
• Use citation management software such as Zotero to keep track of your research citations. 

5. Review the literature. 

Some questions to help you analyze the research: 

• What was the research question you are reviewing? What are the authors trying to discover? 
• Was the research funded by a source that could influence the findings? 
• What were the research methodologies? Analyze the literature review, samples and variables used, results, and conclusions. Does the research seem complete? Could it have been conducted more soundly? What further questions does it raise? 
• If there are conflicted studies, why do you think that is? 
• How are the authors viewed in the field? Are they experts or novices? Has the study been cited?

A literature review is not a summary of the sources but a synthesis of the sources. It is made up of the topics the sources are discussing. Each section of the review is focused on a topic, and the relevant sources are discussed within the context of that topic. 

1. Select the most relevant material from the sources

• Could be material that answers the question directly
• Extract as a direct quote or paraphrase 

2. Arrange that material so you can focus on it apart from the source text itself

• You are now working with fewer words/passages
• Material is all in one place

3. Group similar points, themes, or topics together and label them 

• The labels describe the points, themes, or topics that are the backbone of your paper’s structure

4. Order those points, themes, or topics as you will discuss them in the paper, and turn the labels into actual assertions

• A sentence that makes a point that is directly related to your research question or thesis 

This is now the outline for your literature review.

The most common way that literature reviews are organized is by theme or author. Find a general pattern of structure for the review. When organizing the review, consider the following: 

• the methodology 
• the quality of the findings or conclusions
• major strengths and weaknesses
• any other important information

Writing Tips: 

• Be selective - Select only the most important points in each source to highlight in the review. It should directly relate to the review's focus.
• Use quotes sparingly.
• Keep your own voice - Your voice (the writer's) should remain front and center. .   
• Aim for one key figure/table per section to illustrate complex content, summarize a large body of relevant data, or describe the order of a process
• Legend below image/figure and above table and always refer to them in text

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research that you can later apply to your paper, thesis, or dissertation topic .

There are five key steps to writing a literature review:

• Search for relevant literature
• Evaluate sources
• Identify themes, debates, and gaps
• Outline the structure
• Write your literature review

A good literature review doesn’t just summarize sources—it analyzes, synthesizes , and critically evaluates to give a clear picture of the state of knowledge on the subject.

• Quick Run-through
• Step 1 & 2

When you write a thesis , dissertation , or research paper , you will likely have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

• Demonstrate your familiarity with the topic and its scholarly context
• Develop a theoretical framework and methodology for your research
• Position your work in relation to other researchers and theorists
• Show how your research addresses a gap or contributes to a debate
• Evaluate the current state of research and demonstrate your knowledge of the scholarly debates around your topic.

Writing literature reviews is a particularly important skill if you want to apply for graduate school or pursue a career in research. We’ve written a step-by-step guide that you can follow below.

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.

• Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
• Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
• Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
• Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research problem and questions .

Make a list of keywords

Start by creating a list of keywords related to your research question. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list as you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some useful databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can also use boolean operators to help narrow down your search.

Make sure to read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

You likely won’t be able to read absolutely everything that has been written on your topic, so it will be necessary to evaluate which sources are most relevant to your research question.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models, and methods?
• Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible , and make sure you read any landmark studies and major theories in your field of research.

You can use our template to summarize and evaluate sources you’re thinking about using. Click on either button below to download.

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It is important to keep track of your sources with citations to avoid plagiarism . It can be helpful to make an annotated bibliography , where you compile full citation information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

Prevent plagiarism. Run a free check.

To begin organizing your literature review’s argument and structure, be sure you understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

• Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
• Themes: what questions or concepts recur across the literature?
• Debates, conflicts and contradictions: where do sources disagree?
• Pivotal publications: are there any influential theories or studies that changed the direction of the field?
• Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

• Most research has focused on young women.
• There is an increasing interest in the visual aspects of social media.
• But there is still a lack of robust research on highly visual platforms like Instagram and Snapchat—this is a gap that you could address in your own research.

There are various approaches to organizing the body of a literature review. Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarizing sources in order.

Try to analyze patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organize your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

• Look at what results have emerged in qualitative versus quantitative research
• Discuss how the topic has been approached by empirical versus theoretical scholarship
• Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text , your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, you can follow these tips:

• Summarize and synthesize: give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: don’t just paraphrase other researchers — add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically evaluate: mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: use transition words and topic sentences to draw connections, comparisons and contrasts

In the conclusion, you should summarize the key findings you have taken from the literature and emphasize their significance.

When you’ve finished writing and revising your literature review, don’t forget to proofread thoroughly before submitting. Not a language expert? Check out Scribbr’s professional proofreading services !

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.

There are several reasons to conduct a literature review at the beginning of a research project:

• To familiarize yourself with the current state of knowledge on your topic
• To ensure that you’re not just repeating what others have already done
• To identify gaps in knowledge and unresolved problems that your research can address
• To develop your theoretical framework and methodology
• To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other  academic texts , with an introduction , a main body, and a conclusion .

An  annotated bibliography is a list of  source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a  paper .

Getting started with your Literature Review

• Introduction
• What is a good literature review?
• Future proofing

A literature review is a  comprehensive  and  critical  review of literature that provides the theoretical foundation of your chosen topic.

A review will demonstrate that an exhaustive search for literature has been undertaken. It might be used for a thesis, a report, a research essay or a study. 

A good literature review is a critical component of academic research, providing a comprehensive and systematic analysis of existing scholarly works on a specific topic. Here are the key elements that make up a good literature review:

Focus and clarity: A good literature review has a clear and well-defined research question or objective. It focuses on a specific topic and provides a coherent and structured analysis of the relevant literature.

I n-depth research: A comprehensive literature review involves an extensive search of relevant sources, including academic journals, books, and reputable online databases. It ensures that a wide range of perspectives and findings are considered.

Critical evaluatio n: A good literature review involves a critical assessment of the quality, credibility, and relevance of the selected sources. It evaluates the methodologies, strengths, weaknesses, and limitations of each study to determine their impact on the overall research.

Synthesis and analysis : A literature review should go beyond summarizing individual studies. It involves synthesizing and analyzing the findings, identifying patterns, themes, and gaps in the existing literature, and presenting a coherent narrative that connects different works.

Contribution to knowledg e: A good literature review not only summarizes existing research but also contributes to the knowledge base. It identifies gaps, inconsistencies, or unresolved debates in the field and suggests avenues for further research.

Clear and concise writing : A well-written literature review presents complex ideas in a clear, concise, and organized manner. It uses appropriate language, avoids jargon, and maintains a logical flow of information.

Proper citation and referencing: Accurate citation and referencing of the reviewed sources are crucial for maintaining academic integrity. Following the appropriate referencing style guidelines ensures consistency and allows readers to access the cited works.

In summary, a good literature review demonstrates a thorough understanding of the topic, critically engages with existing literature, and offers valuable insights for future research.

Where should you search?

The Library uses MultiSearch as an access point to our subscriptions and resources. Using MultiSearch is a good place to start. 

You can also search directly in databases. Every discipline has specialist databases and there are also good multidisciplinary databases such as Scopus . Check the Databases page on this guide or ask your Faculty Librarian for advice.

You might also like to consider statistics, government publications or conference proceedings. This will depend on the question you're researching.

What should you read?

Not everything! 

• Skim the title, the keywords, the abstract ... know when to pass on something and move on. 
• Also know when to stop your literature review. When you start seeing the same material repeated in searches, or no new ideas or perspectives, maybe you have it covered. 

Evaluating Literature

You will need to read critically when assessing material for inclusion in your literature review. Each piece of information you look at (whether a journal article, a book, a video, or something else) should be assessed. 

• Is the material current?
• Does it have a bias (why was is published)?
• Is the author authoritative?
• Is the journal well regarded in the field (peer reviewed journals are  the gold standard but other journals are worthy too). 
• Does it provide enough coverage of the topic, or is it basic?
• Will books or journal articles be most useful for your interest area - or do you need to find other materials like government publications, or primary sources?

Analyse the Literature 

Once you've read widely on your subject, stop to consider what new insights this knowledge has provided. 

• Can you see any ideas emerging more strongly than others?
• Have you changed your position since starting your reading? Perhaps the evidence has made you reconsider your starting viewpoint - or it might have made you more committed to it. However, you should read with an open mind, and be prepared to change your thinking if the evidence points that way.
• Make note of a few points every time you read something. Key arguments or themes. Perhaps a note of ideas you'd like to explore more. You might want to attach this information in the same file we've mentioned in the 'future proofing' tab. 

Keep a search diary

Set up a document or spreadsheet to record where you've searched, and also the search strategies you've used. Record the search terms and also the places which have served you well. For instance, is there a particular database which had good coverage?

You may need to repeat searches in the future and this information will help. It might also be requested by your supervisor. 

Saving alerts

There are many options for setting up alerts which will help you keep track of new publications by a journal, or an author who is key in your research area, or even when other people cite the papers you have noted (maybe their work will be of interest to you).

These include: 

• Table of contents (TOC)
• Citation alerts
• Topic or subject alerts
• Author alert

Developing a comprehensive search strategy

• Before you start

1. Consider the guidance in the "getting started" box above before starting your search. 

2. Develop your research question or need.

3. Set up your search diary to record your progress and as a reference guide to come back to. 

1. Identify the  major concepts  from your  research question or topic.

Let's say that our topic is:  How do alternative energy sources play a role in climate change?   

The major concepts will be

• a lternative energy sources
• climate change

2. List  synonyms or alternative terms  for each concept and organise them in a table like the one below - using a column for each major concept. Use as many columns as you have major concepts.

Tools and tips to assist with this process:   

• Run  scoping searches  for your topic in your favourite database or databases such as Google Scholar or Scopus to identify how the literature can express your concepts. Scan titles, subject headings (if any) and abstracts for words describing the same things as your major concepts.
• Text mining tools  including  PubMed Reminer  especially if you are using a database with MeSH such as Medline or Cochrane. There are many others however.
• As you find something new,  add it to the appropriate column on your list  to incorporate later in your search.

Create your search strategy from the concepts, synonyms, phrases etc in your Concept Grid 

Identify the best databases for your topic. Check the databases tab  in the left menu on this Guide.

N.B.The syntax/search tools for your search may depend on the particular database you are searching in. Most databases have a Help screen to assist.  

However, the majority of databases will use Boolean operators (AND, OR, NOT)  and other commonly used search tools :

• Use "OR" to connect each of your synonyms (eg "climate change" OR "global warming")
• Use "AND" to connect each of your concepts.
• (Use "NOT" to exclude terms - but these should be used sparingly as they can knock out useful results.)
• Use the Truncation symbol * at the end of word roots which might have alternative endings eg: manag* will retrieve: manage; management; managing, managerial etc.
• Use quotes to keep together words of phrases (eg "climate change")
• Group your concepts algebraically using parentheses. 
• Consider, is your term alternatively expressed as two words? (eg hydro electricity or hydroelectricity (you should include both!))

So with our question/topic:  How do alternative energy sources play a role in climate change?

After identifying our major concepts and synonyms for each and employing some of the tools mentioned above, our constructed search strategy might look something like this:

("alternative energ*" OR "wind power" OR "Solar power" OR "Solar energy" OR Renewabl* OR geothermal OR hydroelectricity OR "hydro electricity") AND ("climate change" OR "global* warm*" or "greenhouse gas*" or "green house gas*")

3. Be prepared to revise, reassess and refine  your search strategies after you have run your initial searches to ensure you get the best possible results. If you retrieve too many false results or "noise", try to analyse why. For example, you may have used a word which has alternative meanings.

If you have too many results, you can either add another concept or remove some synonyms

If you have too few results, try searching with fewer concepts (identify the least most important to omit) or add more synonyms.

Your  Faculty or Clinical Librarian  will be able to assist with this process.

Psychology - How to Write a Literature Review

In-text citations.

When you use words (direct quotes) or ideas (paraphrases) from other authors in your paper, you must note them with in-text citations.  With APA style, in-text citations can be parenthetical (enclosed in parentheses) or narrative (the author name is incorporated as part of the text).  In both styles, the author’s last name and the year of publication must appear in the sentence. 

Parenthetical example:

One scholar argued that it is impossible to measure social class (Calvert, 1982).

Narrative example:

• Author-Date In-Text Citations from APA Style See chart with examples for multiple authors, group authors and sources with no publication date.

References Page

TIP: Library databases will format citations for you.  When you find a good article, always make sure to copy and paste the citation!  If you are using other sources, like books or websites, you can follow the format examples below or use a citation generator like Citation Machine.

The Literature Review

A literature review is:

1) A list of books and journal articles,

2) on a specific topic,

3) grouped by theme,

4) and evaluated with regard to your research. This evaluation would identify connections, contradictions and gaps in the literature you have found.

The purpose of a literature review, therefore, is:

1) To get a feel for the agreed academic opinion on the subject (the connections).

2) To discover the disagreements on the subject (the contradictions).

3) To find opportunities, (the gaps), for developing and expressing your own opinions.

The classic pattern of academic arguments is

THESIS, ANTITHESIS, SYNTHESIS

An Idea (Thesis) is proposed, an opposing Idea (Antithesis) is proposed, and a revised Idea incorporating (Synthesis) the opposing Idea is arrived at. This revised idea sometimes sparks another opposing idea, another synthesis, and so on…

If you can show this pattern at work in your literature review, and, above all, if you can suggest a new synthesis of two opposing views, or demolish one of the opposing views, then you are almost certainly on the right track.

Steps in compiling a literature review are:

1) Select a specific topic (the more focussed, the better, or you’ll go on for ever).

2) Collect the most relevant (usually "peer reviewed") books and articles.

3) Read/skim them, using the abstract (a short summary attached to the article).

4) Group the articles into the sub-themes of your topic.

5) Identify within each sub-theme those points on which the articles agree, those points on which they disagree, and those points which they don’t cover at all.

1) Choosing your topic

Seek advice from a lecturer or tutor on this, if a topic is not already assigned. It is very common for students to bite off more than they can chew, simply because they have not realised the full breadth and complexity of an apparently simple topic. It is better to cover a tiny topic perfectly, than a huge topic superficially.

Look for a topic on which there is polarised opinion. It often helps to pick one in which a question is being asked, for example: Is a particular taxation policy beneficial or disadvantageous to a developing country?

When authors disagree, this provides an opportunity for you to enter the debate and argue for one side or another in your essay. Taking a hatchet to someone’s opinions (a) gives you something to write about, (b) is fun, (c) is the foundation of much modern scholarly writing.

2) Collect the most relevant (usually "peer reviewed") articles and books

The three tools for finding these books and articles are, in this order:

(a) the relevant section of a good subject encyclopedia, which usually describes the development of the discourse on that subject, gives you an overview of the territory, and ends with a bibliography of the key works on that field. 

(b) the library catalogue and

(c) the library databases of electronic journal articles.

Before you search them, spend a minute thinking about the best terms to use. Make a list of alternative words that describe your subject, and also think about general terms and more specific terms. This is important because the journal databases are good for finding very specific terms in articles, but the library catalogue tends to use more general terms.

To access the library catalogue go to www.lib.uct.ac.za and click on "Catalogue".

If you find a good book reference, scroll down to the bottom of the reference and you will find the subject terms the library cataloguers have assigned to it. Click on that term to call up more books just like the one you have found.

A quick way to check the relevance of any books you find is to glance at the table of contents, the introduction and any descriptive blurbs on the back cover. The index at the back of the book not only helps you dive to very narrow topics in the book, but also gives you an indication of how much attention (i.e. how many pages) the book spends on that specific topic.

If you are satisfied with the book, look at the bibliography in the back – this can help identify other relevant sources. Following a chain of references in a bibliography like this, whether in a book or a journal article, is one of the most basic techniques of scholarship – find something that is relevant and look at the sources it used.

The library’s journal databases are particularly helpful for literature reviews. Journal articles are short and cover very specific topics, so they are more digestible than books and more likely to deal exactly with your topic. They are also quicker to publish than books and so are more likely to be up to date.

To find journal articles by subject go to the library home page at www.lib.uct.ac.za and select "Databases."

Many of these databases allow you to restrict your search to "Peer Reviewed" journals only – these are the most scholarly journals, for which each article has to be vetted by other academics before it is accepted.

Many of our databases are Full Text – so you can usually get the whole article on your desktop for downloading, e-mailing or printing – you don’t have to find it in print on the shelves.

While you can search the Research Portal, or individual journal databases, as simply as you search Google, you can also type in very precise searches by using And, Or, Not operators, Wildcards and Logical Brackets.

An example of such a search would be:

Information Technology AND Brain Drain AND (Employ* OR Jobs OR Labo?r) NOT United States

The AND operator narrows a search – all listed elements must be mentioned in each article: in this example we want articles that cover both Information Technology AND the Brain Drain.

The OR operator expands a search – any of the listed elements must be mentioned in each article: in this example we wanted Information Technology Brain Drain articles that discussed either Employment or Jobs or Labour. The OR operator is useful for dealing with alternative terms which different authors might use when writing on a similar topic.

The Brackets tie the options to the required material. In this example they make sure that any articles we get on labour or employment are concerned with Information Technology and the Brain Drain. If we didn’t have brackets here the search would just bring up every reference to labour in the database, whether relevant to Information Technology or not.

The Wildcards, * and ?, expand a search: The * deals with related words. In this example Employ* means that we get all words starting with "Employ…" – such as Employment, Employee, Employees, Employers…

The ? fills in a missing letter, and is used for covering alternative spellings in British and American English, both Labour and Labor in this example.

NOT weeds out anything you’ve got too much of. Many of our databases are American products, for example, and you can often be flooded with reports on the American situation unless you weed it out.

3) Read/Skim the articles, using their abstracts

Most of the articles will have an abstract. This is a short paragraph at the head of the article that lists the main facts and arguments in each article. By reading these you will quickly get the gist of what each article is about and where it fits into the pattern you are building up in your literature survey.

How many books and articles should you have? It’s wise to check this with your lecturer or tutor. In general, though, your aim is not to cover every single book or article, but every major opinion or theme on the topic. Many of the books or articles will add very little that is new.

Therefore a short list of really scholarly, relevant, comprehensive articles is often more effective than a list of hundreds of superficial or tangential articles.

What you are ideally looking for are the "seminal" articles (seed articles) on which most of the other authors are basing their work.

4) Group the Articles into the themes and sub-themes of your topic

Obviously, it helps to have a structure in mind already, but the articles you find will often help to suggest a structure or cause you to redesign your existing one.

Herewith a hard-learned tip:

There are tides and seasons in academic publishing – a topic is often hot for a few months, then dies, then is revived to be attacked from a different angle, then dies, then is revived again to be discussed from a third angle… remember, Thesis, Antithesis and Synthesis?

This has two implications for studying the results on a database search:

Just because there is nothing much in the recent articles does not mean that it was not hot a few months or years ago, so scroll back in time down the list, or jump right to the earliest reference and scroll up through time to look for a hot spot.

The tides of article titles often tell a story that can help you shape your literature review.

For example, in a list of journal articles on Information Technology and Employment you might find that:

The earliest articles are all about how hard it is to find skilled IT workers.

Later you get articles about UK and US firms desperately recruiting school-leavers and training them in IT skills on the job.

A year later you get articles about how countries like India and South Africa are doing the same thing.

And not long after that you get articles about India and South Africa having a huge, skilled IT workforce, working far more cheaply than the US and UK workforce, and lots of UK and US projects being outsourced to them.

Then you get complaints about unemployment in the IT sector in the UK and USA.

Then you get stories about how employers in the UK and USA have become very choosy about whom they employ, insisting on really good academic training, loads of experience and very-specialised skills.

Then you get the latest stories which are all about how new IT entrants, without that experience, start packing their bags to gain experience elsewhere…

See? Story!

Many database lists of academic articles tell this sort of story when they are looked at in date order. Either they reflect swings in world events or they are reflecting swings in academic debate and opinion. Seeing such a story in the literature is a great help in structuring any literature review.

In particular, look out for the major triggers of such changes: When did the first swing to a new track happen, and what event or article provoked it?

When you find an article that has provoked a major swing, or started a whole new debate, then you are looking at the "Seminal" (Seed) article that I mentioned earlier. This sort of article is often the best sort of article to identify in a literature review – many of the other articles will just build on, comment on, or attack its basic arguments.

Using a Citation Database

If you find a seed article, or any other really good article, we have a magic database, called the ISI Citation Database, which can find all the other articles which have cited that article, either because they support it or because they disagree with it.

The ISI Citation Database is on our database list under ISI WEB OF SCIENCE. There are three versions of it, covering the Sciences, Social Sciences, and Arts and Humanities. You can search all three at once.

Go to "Cited Ref Search" and type in the author’s last name, the journal in which his article appeared and the year it appeared in the appropriate boxes. This will bring up the authors and articles that have followed or disagreed with that author.

Unfortunately this database is not full text, but you can often get the full text of the articles off one or other of our alternative databases.

It is also worth bearing in mind that the PsycInfo database, the main database for Psychology, has a Citation Searching component, which does this job for books and articles on the PsycInfo database.

Another way of doing a citation search is to download Harzing's Publish or Perish software from http://www.harzing.com/pop.htm . This does a lovely job of tracing citations on Google Scholar.

6) Identify within each sub-theme those points on which the articles agree, those points on which they disagree, and those points which they don’t cover at all.

The abstracts can help with this, of course. The main trick is coming up with, or spotting, the sub themes and that is simply a matter of brain work. But if it is done well, and you have taken the trouble to find good sources, then you will find, quite magically, that you have constructed the skeleton and a good bit of the flesh and blood of your essay or research project.

In fact, a good literature review can result in an essay that virtually writes itself.

What is a Literature Review?

The scholarly conversation.

A literature review provides an overview of previous research on a topic that critically evaluates, classifies, and compares what has already been published on a particular topic. It allows the author to synthesize and place into context the research and scholarly literature relevant to the topic. It helps map the different approaches to a given question and reveals patterns. It forms the foundation for the author’s subsequent research and justifies the significance of the new investigation.

A literature review can be a short introductory section of a research article or a report or policy paper that focuses on recent research. Or, in the case of dissertations, theses, and review articles, it can be an extensive review of all relevant research.

• The format is usually a bibliographic essay; sources are briefly cited within the body of the essay, with full bibliographic citations at the end.
• The introduction should define the topic and set the context for the literature review. It will include the author's perspective or point of view on the topic, how they have defined the scope of the topic (including what's not included), and how the review will be organized. It can point out overall trends, conflicts in methodology or conclusions, and gaps in the research.
• In the body of the review, the author should organize the research into major topics and subtopics. These groupings may be by subject, (e.g., globalization of clothing manufacturing), type of research (e.g., case studies), methodology (e.g., qualitative), genre, chronology, or other common characteristics. Within these groups, the author can then discuss the merits of each article and analyze and compare the importance of each article to similar ones.
• The conclusion will summarize the main findings, make clear how this review of the literature supports (or not) the research to follow, and may point the direction for further research.
• The list of references will include full citations for all of the items mentioned in the literature review.

Key Questions for a Literature Review

A literature review should try to answer questions such as

• Who are the key researchers on this topic?
• What has been the focus of the research efforts so far and what is the current status?
• How have certain studies built on prior studies? Where are the connections? Are there new interpretations of the research?
• Have there been any controversies or debate about the research? Is there consensus? Are there any contradictions?
• Which areas have been identified as needing further research? Have any pathways been suggested?
• How will your topic uniquely contribute to this body of knowledge?
• Which methodologies have researchers used and which appear to be the most productive?
• What sources of information or data were identified that might be useful to you?
• How does your particular topic fit into the larger context of what has already been done?
• How has the research that has already been done help frame your current investigation ?

Literature reviews made easy

Turn that jumble of notes and ideas into a well-organized draft with these five strategies.

By Cassandra Willyard

Print version: page 28

Alarm, terror, worry, despair, panic. Do those words describe how you feel about writing your dissertation? If so, you're not alone. The dreaded doctoral dissertation can inspire fear in even the most courageous students.

After you've selected a topic, one of the first major tasks is writing the literature review — the section some experts say is the most difficult and time-consuming. Unlike the methods and results sections, which follow a highly regimented format, the literature review gives students more latitude to develop their own ideas, says Sharon Foster, PhD, a psychologist at Alliant International University and co-author of "Dissertations And Theses from Start to Finish: Psychology and Related Fields" (1993). "You're not just summarizing what's known," Foster says. "You're also trying to figure out what needs to be known to advance the science."

That means critically evaluating the literature and looking for holes, unanswered questions and methodological weaknesses.

Here are five strategies to keep you focused and productive as you tackle the first section of your dissertation:

Get Organized

To conduct a thorough review of the literature, you'll need to read dozens of papers. Unless you possess supernatural powers of memorization, you'll want to create a system for keeping track of the important information. What kind of system is up to you. "There is no template," says Joan Bolker, EdD, author of "Writing Your Dissertation in Fifteen Minutes a Day: A Guide to Starting, Revising, and Finishing Your Doctoral Thesis" (1998). "You have to look at who you are. You have to figure out what's going to fit for you."

For example, if you're the type of student who makes detailed outlines, keeps immaculate files and thinks organizational software is fun, approach your dissertation with the same organizational gusto that you approach the rest of your life. If you're technologically savvy, use the latest smartphone app to keep track of your notes. But if organization doesn't come naturally, keep your system simple. A complex method of index cards and color-coded tabs may make you feel overwhelmed. Even keeping separate, albeit messy, piles can help tame the chaos. You don't have to be an organizational guru to write a dissertation, Bolker says. "I've had several [students who were] slobs who wrote fantastic dissertations."

Whatever system you choose, keep track of your citations. You don't want to be one of the students "scurrying around the library to look up the references" right before the deadline, Bolker notes.

Stay Focused

Students often cast too wide a net when they start their literature reviews, Foster says. "They think they have to write about everything they've read." The result is a huge literature review with too much background and not enough information about your specific research topic. If your dissertation is on relational aggression among elementary school kids, focus in quickly on the type of aggression you're interested in and the age group rather than writing 20 pages of background on aggression, Foster says.

To help narrow your focus, Foster recommends writing the end of the literature review — the part directly relevant to your research question — first. "Then go back and write your introductory materials," she says.

Set a Schedule

Writing is a creative process, but that doesn't mean you should only work when inspiration strikes, says Kjell Rudestam, PhD, associate dean at Fielding Graduate University and author of "Surviving Your Dissertation: A Comprehensive Guide to Content and Process, 3rd edition" (2007). Instead, set aside time to work on your literature review. How much time? That depends on the requirements of your department and how quickly you work. "Some [departments] prefer a very broad and comprehensive review, whereas others prefer a review that is more publication-ready," Rudestam says. The average review may take six months to write and require multiple revisions. "If you don't schedule some time for the dissertation," he says, "it will slip into the background."

Seek Feedback Early and Often

Don't avoid your dissertation committee. Many students do, Rudestam says, because they're afraid that the committee members will raise questions and create more work for them. But you need that kind of feedback. "Typically, it's the committee members, especially the chair of the committee, who have the most awareness and knowledge about the available literature," he says. So your committee can be a valuable resource if you need help figuring out which topics to cover in your literature review or identifying key studies. A student who gets lots of critical feedback early on is more likely to end up with "a dissertation that's bulletproof," Rudestam says.

Seek advice, but don't be afraid to take only what you need. "Three [committee] members are likely to give three different sorts of advice and drive the writer nuts," Bolker says.

Find Your Voice

One of the biggest challenges students face is "making the work their own," Rudestam says. When students write a first draft of the literature review, they often rely too heavily on the opinions of others. "Smith said this. Jones did this. Schwartz thinks this," he says. "You wonder where the author is." Instead of citing an exhaustive list of articles, identify the argument you want to make and then select only the papers that are relevant — those that either support your argument or dispute your hypothesis.

The process of writing a dissertation's literature review is undoubtedly labor-intensive, but it can also be immensely rewarding. "I've had a lot of students who have started out dreading doing a dissertation," Rudestam says. By the end, however, they regard their dissertation as "the most meaningful thing that they did with their graduate studies."

The APA definition of a literature review (from http://www.apa.org/databases/training/method-values.html ):

 Survey of previously published literature on a particular topic to define and clarify a particular problem; summarize previous investigations; and to identify relations, contradictions, gaps, and inconsistencies in the literature, and suggest the next step in solving the problem.

 Literature Reviews should:

• Key concepts that are being researched
• The areas that are ripe for more research—where the gaps and inconsistencies in the literature are
• A critical analysis of research that has been previously conducted
• Will include primary and secondary research
• Be selective—you’ll review many sources, so pick the most important parts of the articles/books.
• Introduction: Provides an overview of your topic, including the major problems and issues that have been studied.
• Discussion of Methodologies:   If there are different types of studies conducted, identifying what types of studies have been conducted is often provided.
• Identification and Discussion of Studies: Provide overview of major studies conducted, and if there have been follow-up studies, identify whether this has supported or disproved results from prior studies.
• Identification of Themes in Literature: If there has been different themes in the literature, these are also discussed in literature reviews.   For example, if you were writing a review of treatment of OCD, cognitive-behavioral therapy and drug therapy would be themes to discuss.
• Conclusion/Discussion—Summarize what you’ve found in your review of literature, and identify areas in need of further research or gaps in the literature.

Because literature reviews are a major part of research in psychology, Psycinfo allows you to easily limit to literature reviews.  In the advanced search screen, you can select "literature review" as the methodology.

Now all you'll need to do is enter your search terms, and your results should show you many literature reviews conducted by professionals on your topic.

When you find an literature review article that is relevant to your topic, you should look at who the authors cite and who is citing the author, so that you can begin to use their research to help you locate sources and conduct your own literature review.  The best way to do that is to use the "Cited References" and "Times Cited" links in Psycinfo, which is pictured below.

This article on procrastination has 423 references, and 48 other articles in psycinfo are citing this literature review.  And, the citations are either available in full text or to request through ILL.  Check out  the article "The Nature of Procrastination" to see how these features work.

By searching for existing literature reviews, and then using the references of those literature reviews to begin your own literature search, you can efficiently gather the best research on a topic.  You'll want to keep in mind that you'll need to summarize and analyze the articles you read, and won't be able to use every single article you choose.

You can use the search box below to get started.

What is a Literature Review?

If this is your first time having to do a literature review, you might be wondering what a "literature review" actually is. Typically, this entails searching through various databases to find peer-reviewed research within a particular topic of interest and then analyzing what you find in order to situate your own research within the existing works.

• A literature review is a critical, analytical summary and synthesis of the current knowledge of a topic. As a researcher, you collect the available literature on a topic, and then select the literature that is most relevant for your purpose. Your written literature review summarizes and analyses the themes, topics, methods, and results of that literature in order to inform the reader about the history and current status of research on that topic.

What purpose does a literature review serve?

• The literature review informs the reader of the researcher's knowledge of the relevant research already conducted on the topic under discussion, and places the author's current study in context of previous studies.
• As part of a senior project, the literature review points out the current issues and questions concerning a topic. By relating the your research to a knowledge gap in the existing literature, you should demonstrate how his or her proposed research will contribute to expanding knowledge in that field.
