Writing a Literature Review

The literature review summarizes the arguments and ideas of others, and compares existing knowledge on a topic

  • identifies major themes, concepts, and researchers on a topic
  • identifies critical gaps or controversies in the literature
  • identifies further research questions that logically come out of the previous studies
  • provides the historical background for your research
  • describes, summarizes and critically evaluates each source

The process

  • select a topic; state it as a well-defined, focused question; write down terms related to your topic; these will come in handy later
  • decide on the details for your review: how many studies do you need to look at? How many years should it cover? If an assignment, is there a specific number of resources required? 
  • search the literature in subject or content specific databases
  • consider what themes or issues connect your sources together; do they present one or different solutions?
  • should you include Grey Literature sources? That is, material that is not published commercially, such as reports written by government organizations, theses and dissertations (Dissertations & Theses Global), conference proceedings, etc.
