What is a review of literature?

The format of a review of literature may vary from discipline to discipline and from assignment to assignment.

A review may be a self-contained unit — an end in itself — or a preface to and rationale for engaging in primary research. A review is a required part of grant and research proposals and often a chapter in theses and dissertations.

Generally, the purpose of a review is to analyze critically a segment of a published body of knowledge through summary, classification, and comparison of prior research studies, reviews of literature, and theoretical articles.

Writing the introduction

In the introduction, you should:

  • Define or identify the general topic, issue, or area of concern, thus providing an appropriate context for reviewing the literature.
  • Point out overall trends in what has been published about the topic; or conflicts in theory, methodology, evidence, and conclusions; or gaps in research and scholarship; or a single problem or new perspective of immediate interest.
  • Establish the writer’s reason (point of view) for reviewing the literature; explain the criteria to be used in analyzing and comparing literature and the organization of the review (sequence); and, when necessary, state why certain literature is or is not included (scope).

Writing the body

In the body, you should:

  • Group research studies and other types of literature (reviews, theoretical articles, case studies, etc.) according to common denominators such as qualitative versus quantitative approaches, conclusions of authors, specific purpose or objective, chronology, etc.
  • Summarize individual studies or articles with as much or as little detail as each merits according to its comparative importance in the literature, remembering that space (length) denotes significance.
  • Provide the reader with strong umbrella sentences at beginnings of paragraphs, signposts throughout, and brief so what summary sentences at intermediate points in the review to aid in understanding comparisons and analyses.

Writing the conclusion

In the conclusion, you should:

  • Summarize major contributions of significant studies and articles to the body of knowledge under review, maintaining the focus established in the introduction.
  • Evaluate the current state of the art for the body of knowledge reviewed, pointing out major methodological flaws or gaps in research, inconsistencies in theory and findings, and areas or issues pertinent to future study.
  • Conclude by providing some insight into the relationship between the central topic of the literature review and a larger area of study such as a discipline, a scientific endeavor, or a profession.

1.04 How to write a literature review

What is a literature review?

The aim of a literature review is to show your reader (your tutor) that you have read, and have a good grasp of, the main published work concerning a particular topic or question in your field.

Writing a good dissertation literature review the purpose of finding

This work may be in any format, including online sources. It may be a separate assignment, or one of the introductory sections of a report, dissertation or thesis. In the latter cases in particular, the review will be guided by your research objective or by the issue or thesis you are arguing and will provide the framework for your further work.

It is very important to note that your review should not be simply a description of what others have published in the form of a set of summaries, but should take the form of a critical discussion, showing insight and an awareness of differing arguments, theories and approaches. It should be a synthesis and analysis of the relevant published work, linked at all times to your own purpose and rationale.

According to Caulley (1992) of La Trobe University, the literature review should:

• compare and contrast different authors’ views on an issue
• group authors who draw similar conclusions
• criticise aspects of methodology
• note areas in which authors are in disagreement
• highlight exemplary studies
• highlight gaps in research
• show how your study relates to previous studies
• show how your study relates to the literature in general
• conclude by summarising what the literature says

The purposes of the review are:

• to define and limit the problem you are working on
• to place your study in an historical perspective
• to avoid unnecessary duplication
• to evaluate promising research methods
• to relate your findings to previous knowledge and suggest further research

A good literature review, therefore, is critical of what has been written, identifies areas of controversy, raises questions and identifies areas which need further research.

Structure of the literature review

The overall structure of your review will depend largely on your own thesis or research area. What you will need to do is to group together and compare and contrast the varying opinions of different writers on certain topics. What you must not do is just describe what one writer says, and then go on to give a general overview of another writer, and then another, and so on. Your structure should be dictated instead by topic areas, controversial issues or by questions to which there are varying approaches and theories. Within each of these sections, you would then discuss what the different literature argues, remembering to link this to your own purpose.

Linking words are important. If you are grouping together writers with similar opinions, you would use words or phrases such as:

similarly, in addition, also, again

More importantly, if there is disagreement, you need to indicate clearly that you are aware of this by the use of linkers such as:

however, on the other hand, conversely, nevertheless

At the end of the review you should include a summary of what the literature implies, which again links to your hypothesis or main question.

You first need to decide what you need to read. In many cases you will be given a booklist or directed towards areas of useful published work. Make sure you use this help. With dissertations, and particularly theses, it will be more down to you to decide. It is important, therefore, to try and decide on the parameters of your research. What exactly are your objectives and what do you need to find out? In your review, are you looking at issues of theory, methodology, policy, quantitive research, or what? Before you start reading it may be useful to compile a list of the main areas and questions involved, and then read with the purpose of finding out about or answering these. Unless something comes up which is particularly important, stick to this list, as it is very easy to get sidetracked, particularly on the internet.

A good literature review needs a clear line of argument. You therefore need to use the critical notes and comments you made whilst doing your reading to express an academic opinion. Make sure that:

• you include a clear, short introduction which gives an outline of the review, including the main topics covered and the order of the arguments, with a brief rationale for this.

• there is always a clear link between your own arguments and the evidence uncovered in your reading. Include a short summary at the end of each section.
Use quotations if appropriate.

• you always acknowledge opinions which do not agree with your thesis. If you ignore opposing viewpoints, your argument will in fact be weaker.

Your review must be written in a formal, academic style. Keep your writing clear and concise, avoiding colloquialisms and personal language. You should always aim to be objective and respectful of others’ opinions; this is not the place for emotive language or strong personal opinions. If you thought something was rubbish, use words such as inconsistent, lacking in certain areas or based on false assumptions! (See Guide 1.21)

When introducing someone’s opinion, don’t use says, but instead an appropriate verb which more accurately reflects this viewpoint, such as argues, claims or states. Use the present tense for general opinions and theories, or the past when referring to specific research or experiments:

Although Trescothick (2001) argues that attack is the best form of defence, Boycott (1969) claims that.

In a field study carried out amongst the homeless of Sydney, Warne (1999) found that.

And remember at all times to avoid plagiarising your sources. Always separate your source opinions from your own hypothesis. making sure you consistently reference the literature you are referring to. When you are doing your reading and making notes, it might be an idea to use different colours to distinguish between your ideas and those of others. (See Guide 1.13).

Here is a final checklist, courtesy of the University of Melbourne:

Selection of Sources

Have you indicated the purpose of the review?
Are the parameters of the review reasonable?
Why did you include some of the literature and exclude others?
Which years did you exclude?
Have you emphasised recent developments?
Have you focussed on primary sources with only selective use of secondary sources?
Is the literature you have selected relevant?
Is your bibliographic data complete?

Critical Evaluation of the Literature

Have you organised your material according to issues?
Is there a logic to the way you organised the material?
Does the amount of detail included on an issue relate to its importance?
Have you been sufficiently critical of design and methodological issues?
Have you indicated when results were conflicting or inconclusive and discussed possible reasons?
Have you indicated the relevance of each reference to your research?

Has your summary of the current literature contributed to the reader’s understanding of the problems?
Does the design of your research reflect the methodological implications of the literature review?

The literature review will be judged in the context of your completed research.
The review needs to further the reader’s understanding of the problem and whether it provides a rationale for your research.
