Facts about Impact Factors

  • Impact Factors are only calculated for journals (not articles or researchers).
  • Impact Factors are calculated by:   
    • selecting a JCR year
    • adding the total # of citations to all items published in the two previous years that were cited in the JCR year
    • divided by the total # of citable items (articles, reviews, and proceedings) published in that two previous years 
  • Impact factors are only available from Journal Citation Reports (JCR).
  • Not every journal has an impact factor.
    • Only journals indexed ISI Citation Indexes.
  • Many subject areas in science and social science are covered in JCR.
