Find Impact Factors & Other Bibliometrics

Journal Impact Factor (Journal Citation Reports, by Clarivate Analytics)
If a journal title is not found in Journal Citation Reports, see if it is included in the Web of Science Master List.  If not, the journal is unlikely to have a Journal Impact Factor since JCR includes only titles from the Master List.  

CiteScore (by Elsevier)

Eigenfactor Score
Eigenfactor Scores through 2015 are freely provided on its web page.  Current Eigenfactor Scores can be found either through Journal Citation Reports or by visiting a journal's web page.  

CWTS Journal Indicators (by Leiden University)

SCImago

Journal Web Sites

Journal-level metrics can often be found on a journal's website if it was given one.  See its "About" section, or "Journal Home," "Overview," or similar areas of the journal web site.  See the example and links below.

A journal's web site should also provide contact information for their editors and editorial board who may be able to advise. 

What if I can't find the Journal Impact Factor or other bibliometric for a journal?

When this happens, it is not necessarily a mark of a poor quality or low impact publication  Here are some reasons a journal may not have one:

  1. Publication norms by discipline:  Fields that rely on peer-reviewed journals for communicating scholarly or creative activity, or those with high citation density (that is, frequently or very highly cite previous works) use journal metrics more than fields that do not.  Many STEM fields use metrics while most in arts and humanities do not; the latter communicates more through monographs (books) or secondary sources, or by making creative works (musical scores, performances, art).

  2. Indexing:  academic publishers (Elsevier or Clarivate Analytics) or organizations (SCImago, CTWS) generate their metrics from indexes that have a list of select journals.  The CiteScore is given to most Elsevier journals and other publications in the Scopus index while a Journal Impact Factor is given to journals indexed in the Web of Science Master List.  If a journal does not have a metric, it may not had been included in one or both of these indexes.

  3. Age of publication:  blbliometrics are generated for a given year by analyzing a work or author's prior years of activity.  If a publication is less than 3 years old, it will not have enough data to create a bibliometric. Also, journals that are included in indexes are evaluated on its characteristics; the length of time it has been published is one consideration for inclusion.

  4. Open Access publications:  its age may be a reason for not having a bibliometric if it is less than 3 years old.  Also, some OA publications may not yet be included in the indexes of major academic publishers.

  5. Location and language of publication: indexes include fewer journals that are published in emerging research nations in proportion to those published in western Europe and North America.  Indexes include more journals published in the English language and include fewer published in other world languages.
