A literature review is:
- An essay based on a list of books and journal articles,
- on a specific topic,
- grouped by theme,
- and evaluated with regard to your research. This evaluation would identify connections, contradictions and gaps in the literature you have found.
Literature reviews should include in-text citations to multiple scholarly articles, which are listed in a bibliography, references list, or works cited list.
The purpose of a literature review is:
- To learn and explore the academic opinions on the subject (the connections).
- To discover the disagreements on the subject (the contradictions).
- To find opportunities (the gaps) for developing and describing your own research.
