Doing the Literature Review

  • collect a comprehensive set of publications on the topic
  • build a picture of the nature and scope of the problem
  • develop a framework for evaluating possible solutions
  • analyse the specific work described in the publications
How comprehensive?   (a.k.a. how many references is enough?)
  • until you are convinced that you have all relevant material
  • some topics may require: one main ref + one general ref
  • other topics may have dozens of relevant publications
  • use your judgement when to stop (and ask supervisor)
