What is a literature review?

A literature review can be just a simple summary of the sources, but it usually has an organizational pattern and combines both summary and synthesis. A summary is a recap of the important information of the source, but a synthesis is a re-organization, or a reshuffling, of that information.

How is a literature review different from an academic research paper?

The main focus of an academic research paper is to develop a new argument, and a research paper will contain a literature review as one of its parts. In a research paper, you use the literature as a foundation and as support for a new insight that you contribute. The focus of a literature review, however, is to summarize and synthesize the arguments and ideas of others without adding new contributions.

How do I know when I can stop?

Literature reviews can be tricky because you don't want to stop before you've found everything relevant to your topic. There are a couple of guidelines for knowing when to stop looking for materials.

1. If you have done steps 1.1-1.3 (below), when you start to see the same articles over again, then you have done your due diligence and can consider your lit review complete.
   1. Searched all relevant databases, using a variety of keywords and subject headings
   2. Mined article bibliographies for their cited references
   3. Looked in Google Scholar or Web of Science to see who has cited those articles
2. Think of the assignment timeline. If you are writing your PhD thesis you can spend more time doing a comprehensive lit review than if you only have a few weeks until an assignment is due. At some point you need to stop.
