How to Writing a Literature Review

A literature review is both a summary and explanation of the complete and current state of knowledge on a limited topic as found in academic books and journal articles. There are two kinds of literature reviews you might write at university: one that students are asked to write as a stand-alone assignment in a course, often as part of their training in the research processes in their ﬁeld, and the other that is written as part of an introduction to, or preparation for, a longer work, usually a thesis or research report. The focus and perspective of your review and the kind of hypothesis or thesis argument you make will be determined by what kind of review you are writing. One way to understand the differences between these two types is to read published literature reviews or the ﬁrst chapters of theses and dissertations in your own subject area. Analyse the structure of their arguments and note the way they address the issues.
Purpose of the Literature Review
- It gives readers easy access to research on a particular topic by selecting high quality articles or studies that are relevant, meaningful, important and valid and summarizing them into one complete report
- It provides an excellent starting point for researchers beginning to do research in a new area by forcing them to summarize, evaluate, and compare original research in that speciﬁc area
- It ensures that researchers do not duplicate work that has already been done
- It can provide clues as to where future research is heading or recommend areas on which to focus
- It highlights key ﬁndings
- It identiﬁes inconsistencies, gaps and contradictions in the literature
- It provides a constructive analysis of the methodologies and approaches of other researchers
Content of the Review
The introduction explains the focus and establishes the importance of the subject. It discusses what kind of work has been done on the topic and identiﬁes any controversies within the ﬁeld or any recent research which has raised questions about earlier assumptions. It may provide background or history. It concludes with a purpose or thesis statement. In a stand-alone literature review, this statement will sum up and evaluate the state of the art in this ﬁeld of research; in a review that is an introduction or preparatory to a thesis or research report, it will suggest how the review ﬁndings will lead to the research the writer proposes to undertake.
Often divided by headings/subheadings, the body summarizes and evaluates the current state of knowledge in the ﬁeld. It notes major themes or topics, the most important trends, and any ﬁndings about which researchers agree or disagree. If the review is preliminary to your own thesis or research project, its purpose is to make an argument that will justify your proposed research. Therefore, it will discuss only that research which leads directly to your own project.
The conclusion summarizes all the evidence presented and shows its signiﬁcance. If the review is an introduction to your own research, it highlights gaps and indicates how previous research leads to your own research project and chosen methodology. If the review is a stand-alone assignment for a course, it should suggest any practical applications of the research as well as the implications and possibilities for future research.
Nine Steps To Writing A Literature Review
1. Find a Working Topic
Look at your speciﬁc area of study. Think about what interests you, and what is fertile ground for study. Talk to your professor, brainstorm, and read lecture notes and recent issues of periodicals in the ﬁeld.
2. Review the Literature
- Using keywords, search a computer database. It is best to use at least two databases relevant to your discipline
- Remember that the reference lists of recent articles and reviews can lead to valuable papers
- Make certain that you also include any studies contrary to your point of view
3. Focus Your Topic Narrowly and Select Papers Accordingly
Consider the following:
- What interests you?
- What interests others?
- What time span of research will you consider?
Choose an area of research that is due for a review.
4. Read the Selected Articles Thoroughly and Evaluate Them
- What assumptions do most/some researchers seem to be making?
- What methodologies do they use? what testing procedures, subjects, material tested?
- Evaluate and synthesize the research ﬁndings and conclusions drawn
- Note experts in the ﬁeld: names/labs that are frequently referenced
- Note conﬂicting theories, results, methodologies
- Watch for popularity of theories and how this has/has not changed over time
5. Organize the Selected Papers By Looking For Patterns and By Developing Subtopics
Note things such as:
- Findings that are common/contested
- Two or three important trends in the research
- The most inﬂuential theories
6. Develop a Working Thesis
Write a one or two sentence statement summarizing the conclusion you have reached about the major trends and developments you see in the research that has been done on your subject.
7. Organize Your Own Paper Based on the Findings From Steps 4 & 5
Develop headings/subheadings. If your literature review is extensive, ﬁnd a large table surface, and on it place post-it notes or ﬁling cards to organize all your ﬁndings into categories. Move them around if you decide that (a) they ﬁt better under different headings, or (b) you need to establish new topic headings.
8. Write the Body of the Paper
Follow the plan you have developed above, making certain that each section links logically to the one before and after, and that you have divided your sections by themes or subtopics, not by reporting the work of individual theorists or researchers.
9. Look At What You Have Written; Focus On Analysis, Not Description
Look at the topic sentences of each paragraph. If you were to read only these sentences, would you ﬁnd that your paper presented a clear position, logically developed, from beginning to end? If, for example, you ﬁnd that each paragraph begins with a researcher's name, it might indicate that, instead of evaluating and comparing the research literature from an analytical point of view, you have simply described what research has been done. This is one of the most common problems with student literature reviews. So if your paper still does not appear to be deﬁned by a central, guiding concept, or if it does not critically analyse the literature selected, then you should make a new outline based on what you have said in each section and paragraph of the paper, and decide whether you need to add information, to delete off-topic information, or to restructure the paper entirely.
For example, look at the following two passages and note that Student A is merely describing the literature and Student B takes a more analytical and evaluative approach, by comparing and contrasting. You can also see that this evaluative approach is well signalled by linguistic markers indicating logical connections (words such as "however," "moreover") and phrases such as "substantiates the claim that," which indicate supporting evidence and Student B's ability to synthesize knowledge.
