What type of publications am I using ?What discipline am I working in?
  • Ask these Questions  How good was my information seeking? Has my search been wide enough to ensure I have found all the relevant material? Is number of sources I have used appropriate for the length of my research?  Have I critically analyzed the literature I use? Do I follow through a set of concepts and questions, comparing items to each other in the ways they deal with them?
  • Ask these Questions  How I cited and discussed studies contrary to my perspective?  Will the reader find my literature review relevant, appropriate and useful?
  • Literature Review  If the problem has historical background, begin with the earliest references  Avoid the extraneous details of literature.  Do a brief review of information, not a comprehensive report.  Always refer to original source.  If you find something of interest in a quotation find the original publication and ensure that you understand it.
