The purpose of a literature review is to:
- Provide a foundation of knowledge on a topic
- Identify areas of prior scholarship to prevent duplication and give credit to other researchers
- Identify inconstancies: gaps in research, conflicts in previous studies, open questions left from other research
- Identify the need for additional research (justifying your research)
- Identify the relationship of works in the context of their contribution to the topic and other works
- Place your own research within the context of existing literature, making a case for why further study is needed.
