Journal Impact

What is SJR?

SCImago Journal & country Rank (SJR) is a metric used to evaluate the impact of academic journals. Developed by SCImago, it is based on data from the Scopus database and reflects the journal's prestige and influence.

  • weighted by the prestige of a journal
  • accounts for both the number of citations received by a journal and the importance of the journals where such citations come from
  • prevents excessive journal self-citation (maximum 33% self-citation) 
  • 3-year window

What is SNIP?

SNIP takes into account the field of research and the citation patterns within that field to provide a normalized measure of a journal's impact
particularly useful when comparing journals from different disciplines.

  • accounts for differences in citation practices across various disciplines, allowing for a fair comparison between journals in different fields
  • 3-year window
  • allows direct comparison of sources in different subject fields
  • based on data from Scopus
