It is not enough to simply summarize the research literature. You need to demonstrate that you understand the relevance and significance of the publications you reviewed and how they relate to each other.
See these guides for information on Evaluating and Citing your sources.
Use this Research Organizer to manage your review of the literature on a topic. You can cut and paste it into a Google Spreadsheet and share it with others if you are doing a group project. It will allow you to share your research with each other as you find it, and prevent group members from duplicating efforts. Under columns E-I, you can either summarize your findings from each source or directly quote relevant phrases (be sure to include page numbers where necessary).
