Scopus Journal Analyser

The Scopus Journal Analyzer provides a measure of journal performance. Scopus includes over 21 000 peer-reviewed publications from 5,000 publishers; the Analyzer enables you to compare up to 10 journals simultaneously, back to 1996.

journal metrics

  1. SJR (SCImago Journal Rank) is a prestige measure based on the idea that all citations are not created equal. With SJR, the subject field, quality and reputation have a direct effect on the value of a citation. (About SJR)
  2. SNIP (Source Normalized Impact per Paper) measures citation impact by weighting citations based on the total number of citations in a specific subject field. The impact of a single citation is given higher value in subject areas where citations are less likely, and vice versa. (About SNIP)
