 What are literature reviews?

Literature reviews are literally reviews of the literature ( the academic writing e.g. academic books, journal articles etc. ) that have been published on a particular research topic.  They aim to identify what is already known on the topic at that time.  The steps involved in this research journey are

  • Selecting a research question 
  • Searching the literature that has been published in the area
  • Managing the literature search results
  • Synthesizing the research literature
  • Writing an assessment review
  • Rethinking, refining and reworking your review in an iterative process until you are satisfied

Why are literature reviews necessary?

They are necessary for several reasons. They are an essential part of the research process.  They give an overview of a topic's theoretical background. Researchers use literature reviews to identify gaps in existing knowledge and to set the context for their research studies. Students can be asked to complete a literature review as part of their course to help them understand a topic more deeply. Writing a literature review can enable a student to demonstrate what they have learned about a topic and develop their own connecting ideas within that topic further.
