Why do we need to evaluate journal quality?

Assessing the academic quality of a particular journal or article is important.  It can:

  • Help you determine the scholary worth and relevance to your research. 
  • Affect where you choose to publish your own research.

The JCR "impact factor" historically has been the main factor used to judge the relative importance of a journal in its field.  However, because the index is based on only publications indexed in Web of Science the validity of this measurement is being disputed particularly in non-scientific fields and we are now seeing the other "impact" factors being published.

What is the Journal Citation Reports "Impact factor?"

Using works indexed in the Web of Science, the JCR Journal Impact Factor is the average number of times articles from a journal published in the past two years have been cited in the JCR year.  For example:

  • An Impact Factor of 1.0 means that, on average, the articles published in a journal one or two year ago have been cited one time.
  • An Impact Factor of 2.5 means that, on average, the articles published one or two year ago have been cited two and a half times.

  • Use the links below to find different "impact" factors for a journal, including the JRC Journal Impact Factor. 
  • Go to the journal's web site. Many journals publish their impact factors on their web site.

Are there other ways to evaluate "impact?"

Since one of the main criteria for calulating "impact" is the number of times articles from a journal are cited.
