Publishing in the Life Sciences

Measures of journal impact and prestige

  • Impact Factor - From Journal Citation Reports. Subscription required.
  • CiteScore (Scopus) - Similar concept to the Impact Factor but uses a different calculation. Does not include field normalization (i.e., not adjusted for differences across areas of study). See CiteScore FAQ
  • Eigenfactor - An alternative or complement to the Impact Factor; can also be accessed through InCites Journal Citation Reports
  • SCImago Journal and Country Rank (SJR) - Can filter by subject area/category; developed from information found in Scopus, a subscription-based, multidisciplinary, bibliographic database. Citations are weighted based on subject field, quality/reputation of the journal; self-citations are limited in weight. Free.

See Journal-level metrics (in the Impact Measurements guide maintained by April Colosimo) for additional information
