Bibliometrics and Altmetrics: Measuring the Impact of Knowledge

Learn how to track citations to your research and effectively communicate the impact and significance of your academic work.

DEFINITION: SCImago Journal Rank (SJR)

SCImago Journal Rank (SJR) is a portal that includes the journals and country scientific indicators developed from the information contained in the Scopus database (Elsevier). It is also a prestige metric based on the idea that "all citations are not created equal." With SJR, the subject field, quality and reputation of the journal has a direct effect on the value of a citation. Using the Google Page Rank algorithm, it was developed by a research group from the Consejo Superior de Investigaciones Científicas (CSIC), University of Granada, Extremadura, Carlos III (Madrid) and Alcalá de Henares.

SJR...

  • Is weighted by the prestige of the journal, thereby ‘leveling the playing field’ among journals
  • Eliminates manipulation: raise the SJR ranking by being published in more reputable journals
  • ‘Shares’ a journal’s prestige equally over the total number of citations in that journal
  • Normalizes for differences in citation behavior between subject fields
