Writing a literature review.

This guidance is useful for student undertaking a ‘Critical Literature Review’.

A literature review must do these things;

1. be organized around and related directly to the thesis or research question you are developing.
2. synthesize results into a summary of what is and is not known.
3. identify areas of controversy in the literature.
4. formulate questions that need further research.

Ask yourself questions like these:

1. What is the specific thesis, problem, or research question that my literature review helps to define?
2. What type of literature review am I conducting? Am I looking at issues of theory? methodology? policy? quantitative research (e.g. on the effectiveness of a new procedure)? qualitative research (e.g., studies )?
3. What is the scope of my literature review? What types of publications am I using (e.g., journals, books, government documents, popular media)? What discipline am I working in (e.g., nursing psychology, sociology, medicine)?
4. How good was my information seeking? Has my search been wide enough to ensure I’ve found all the relevant material? Has it been narrow enough to exclude irrelevant material? Is the number of sources I’ve used appropriate for the length of my paper?
5. Have I critically analysed the literature I use? Do I follow through a set of concepts and questions, comparing items to each other in the ways they deal with them? Instead of just listing and summarizing items, do I assess them, discussing strengths and weaknesses?
6. Have I cited and discussed studies contrary to my perspective?
7. Will the reader find my literature review relevant, appropriate, and useful?

Ask yourself questions like these about each book or article you include:

1. Has the author formulated a problem/issue?
2. Is it clearly defined? Is its significance (scope, severity, relevance) clearly established?
3. Could the problem have been approached more effectively from another perspective?
4. What is the author’s research orientation (e.g., interpretive, critical science, combination)?
5. What is the author’s theoretical framework (e.g., psychological, developmental, feminist)?
6. What is the relationship between the theoretical and research perspectives?
7. Has the author evaluated the literature relevant to the problem/issue? Does the author include literature taking positions she or he does not agree with?
8. In a research study, how good are the basic components of the study design (e.g., population, intervention, outcome)? How accurate and valid are the measurements? Is the analysis of the data accurate and relevant to the research question? Are the conclusions validly based upon the data and analysis?
9. In material written for a popular readership, does the author use appeals to emotion, one-sided examples, or rhetorically-charged language and tone? Is there an objective basis to the reasoning, or is the author merely “proving” what he or she already believes?
10. How does the author structure the argument? Can you “deconstruct” the flow of the argument to see whether or where it breaks down logically (e.g., in establishing cause-effect relationships)?
11. In what ways does this book or article contribute to our understanding of the problem under study, and in what ways is it useful for practice? What are the strengths and limitations?
12. How does this book or article relate to the specific thesis or question I am developing?
