Policing & Corrections: Reference Works

Why Reference Works?

Scholarly reference works are useful for the following:

  • An overview of a topic
  • Topic ideas for a paper topic or narrowing your topic
  • Finding keywords for searches 
  • Bibliographies for further research

Reference works are good starting points for research, but are rarely cited in research as secondary sources.
