A literature review is an integrated analysis-- not just a summary-- of scholarly writings related directly to your research question. That is, it represents the literature that provides background information on your topic and shows a correspondence between those writings and your research question.
Lit reviews can be organized in several ways depending on how you want to present the information: chronological, thematic, or methodological.
For additional help and examples, see the UWF Libraries guide for writing a Literature Review.
