What You Need to Know

CiteScore is a brand new (December 2016) product from Elsevier, using citation data from the Scopus database to rank journals.   As with other journal ranking metrics, to compare journals across disciplines requires a "normalized" ranking, which CiteScore provides as a percentile ranking within the journal's subject category. In addition to the CiteScore number and percentile ranking, CiteScore also includes the SJR (Scimago Journal Rank) and SNIP (Source Normalized Impact per Paper) numbers.    

Important Points:

  • Because the CiteScore is based on raw citations counts, comparing CiteScores in different disciplines penalizes journals in fields with naturally low citation numbers.  
  • CiteScore may assign journals to more than one subject category.  Additionally, the selected subject category for CiteScore in some cases has been either incorrect or questionable. (Elsevier is working on correcting this.) 
  • To compare journals across subject areas, CiteScore provides a CiteScore Percentile which normalizes the raw CiteScore within its subject area.  The scale runs from 100 (highest rank) down to 1 (lowest rank).   
  • If a journal has been assigned to more than one subject area, the CiteScore Percentile will be from the subject area in which the journal ranked the highest.
  • CiteScore uses approximately 22,000 journals plus conference papers and reviews indexed in the Scopus database as its source data.  
  • The annual CiteScore covers articles published in the previous three years.
  • CiteScore includes front matter (editorials, news, letters to editors, etc.) in its calculations for how many documents are in each journal; consequently, journals with a lot of front matter, which is generally not cited, have a lower CiteScore (sometimes substantially lower) than their Journal Impact Factor (JIF).   
  • Punctuation in a journal title appears to be complicating the title search; if a journal is not found by its full title, use one or two keywords for the search.  
  • CiteScore is produced by a major publisher (Elsevier) of journals which some have criticized as "conflict of interest."
  • CiteScore determines the overall performance of a journal; it does not predict the performance of any of the individual articles within the journal.  Use other metrics to evaluate articles. 


  • Go to CiteScore
  • Enter the title of the journal in the search title area and click on the title as it appears in the box below.  If having difficulties finding the journal, enter just one or two keywords from the title. 
  • Enter as many journals as you want (one per search) to create a table for comparison. 

  • Directly under each journal title is the subject category in which the journal has been placed.
  • Use the number in the "Highest CiteSource Percentile" for comparison purposes (click on this column header to sort the table by the percentile)

  • To see the details about a specific journal, click on the journal title.
