The goal of a literature review is to find all the relevant publications on a topic and to then summarize and synthesize that information. A literature review can help you find areas where further research is needed, narrow a research topic, or determine if a thesis question is unique. Talk to your advisor for help defining your research question. For help with library resources, talk to your librarian; they can help you find a combination of resources that will result in a comprehensive search.
