Q: How do I do a review of related literature (RRL)?

A review of related literature (RRL) is a detailed review of existing literature related to the topic of a thesis or dissertation. In an RRL, you talk about knowledge and findings from existing literature relevant to your topic. If you find gaps or conflicts in existing literature, you can also discuss these in your review, and if applicable, how you plan to address these gaps or resolve these conflicts through your study.

To undertake an RRL, therefore, you first need to identify relevant literature. You can do this through various sources, online and offline. Ensure you are saving all applicable resources because you will need to mention them in your paper. When going through the resources, make notes and identify key concepts of each resource to describe in the review.

Before starting the review, determine how you want to organize the review, that is, whether you wish to discuss the resources by themes, dates, extent of relevance, and so on.

When writing the review, begin by providing the background and purpose of the review. Then, begin discussing each of the identified resources according to the way you decided to organize them. For each, you can mention the title, author, publication, and date before describing the key concept and points. You may decide to list sections and sub-sections as in this sample or keep it more free-flowing as in this sample. [Note: In case any of these links don’t open, you may need to register yourself on the respective site(s).]

Finally, in the synthesis, you explain how the various concepts of each resource link with each other. You may decide to do this through a table or matrix, as illustrated here.
