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.
