What is a dissertation literature review?

It also provides a context in a research project by evaluating past research on the current research project. Academic resources include journal articles, books, websites articles, other published dissertation projects, etc. A literature review offers new perspectives on the subject matter.

The presentation of your literature review must exhibit the following:

- The use of citations to emphasize the reported work by the author. Citations include:
