Finding Impact Factors via Journal Citation Reports

Print Version PDF File

What are Impact Factors?

Impact factors are a quantitative measure of the frequency with which the “average article” published in a given scholarly journal has been cited in a particular year or period; this is used in citation analysis (definition retrieved from http://exchanges.wiley.com/authors/finding-a-journal-for-your-research-_271.html)

Impact Factor for Journal X = Citations in 2013 to articles published in X in 2011 and 2012

Articles published in X in 2011 and 2012

 

Not all journals have impact factors, and impact factors are not the only indicator of quality. In addition, impact factors vary greatly between subject areas/disciplines.
