A literature review is a systematic survey of the scholarly literature published on a given topic. Rather than providing a new research insight, a literature review lays the groundwork for an in-depth research project analyzing previous research. Type of documents surveyed will vary depending on the field, but can include:
- books
- journal articles,
- theses
- dissertations.
A thorough literature review will also require surveying what librarians call "conference papers," which includes difficult-to-locate documents such as:
- technical reports
- government publications
- working papers
- preprints
