Journal Impact Factor

An impact factor is a way of measuring the relative ranking of a journal within a particular field.  Ranked lists of journals can be used to:

  • Identify prestigious and influential journals in a particular discipline.
  • Identify highly ranked journals in which to publish.
  • Help determine the allocation of research funds.

The Journal Impact Factor is the average number of times an article has been cited in a particular year or period. The first database that created the "impact factor" is Journal Citation Reports (JCR)
