What IS a Literature Review?
A literature review does not present an original argument. The purpose is to offer an overview of what is known about the topic and to evaluate the strength of the evidence on that topic. It usually contains a summary, a synthesis, or an analysis of the key arguments in the existing literature. The literature may come from books, articles, reports, or other formats. Sources may even contradict each other. A literature review also helps distinguish what research has been done and identify what needs further research
Literature Review vs. Research Paper vs. Annotated Bibliography
A literature review:
- Shares experts' various thoughts, ideas and viewpoints about a topic within your field
- Summarizes arguments from various sources pointing out strengths and weaknesses of their arguments
- Sources may contradict each other
A research paper:
- Presents a single thought, idea or argument about a topic
- Explains or argues an idea using research that supports a single conclusion
- Sources used generally support each other
An annotated bibliography:
- Lists citations to books, articles, and documents with each citation followed by a brief descriptive and evaluative paragraph. See Purdue OWL for further information.
