In a literature review you explore research that has come before you and is relevant to your topic. It can help you identify:

Writing Guidelines:
Systematic reviews are not the same as literature reviews; instead, they can be considered an extremely rigorous subset of literature reviews. Generally, systematic reviews take a team of professionals and one to two years to complete, and they usually can't be done for avenues of research which are newly being explored (there needs to be an established body of literature to examine). This makes them very helpful resources if they exist for your topic of interest!
You may wish to peruse UCSF's Systematic Review Guide for information.
If you do decide to do a systematic review, UC Berkeley licenses Covidence, a tool to help you. In Covidence, you can import citations, screen titles and abstracts, upload references, screen full text, create forms for critical appraisal, perform risk of bias tables, complete data extraction, and export a PRISMA flowchart summarizing your review process. As an institutional member, our users have priority access to Covidence support. To access Covidence using the UC Berkeley institutional account, start at this page and follow the instructions.
Now That You Have All Those Articles, How Do You Synthesize Them?
Unlike the annotated bibliography, the literature review does not just summarize each article or book. Instead, they synthesize. Some researchers find it helpful to develop a framework, making a column for each element that they want to compare. The elements vary depending on the research, making it easier to understand the relationships between all the articles and how they relate to your research. Here's one example!
How To Organize and Cite Your Research
Citation management tools help you manage your research, collect and cite sources, and create bibliographies in a variety of citation styles. Each one has its strengths and weaknesses, but any are easier than doing it by hand! The Library offers workshops on Endnote, Zotero, and Refworks. I'm also happy to help arrange a small group workshop, or one on one help with Zotero.
For more information on the various tools available, and more on Zotero, see the "Managing Citations" tab in this guide!
