What is a literature review?
A literature review (or lit review) is an in-depth critical analysis of published scholarly research related to a specific topic. Published scholarly research (the "literature") includes journal articles and books.
A solid lit review must:
- be organized around and related directly to the thesis or research question you're developing
- incorporate results into a summary of what is and is not known
- identify areas of controversy in the literature
- create questions that need further research
