What are Bibliometrics?

Bibliometrics refers to measuring impact by counting citations, specifically by counting how many times a particular work has been cited by other works.

Help With Citation Analysis

The Himmelfarb Health Sciences Library provides access to a number of resources to help you analyze citations:

  • Scopus
    • Click "Analytics" on the blue ribbon above the search bar
    • You can get SJR and SNIP values (see "Journal Impact" tab) for journals and create charts comparing different titles
  • Web of Science
    • Click "Additional Resources" tab at the top of the page
    • Select "Journal Citation Reports" to get access to citation data
  • Quantifying Scholarly Research Impact guide
  • Reference & Instruction Librarian Tom Harrod's guide contains tips on calculating an author- and journal-level metrics (H-index, G-index, Eigenfactor, Scimago Journal Rank, and others) and a case study of two authors.
  • iCite​ 
    • iCite offers bibliometric information for journal articles included in the PubMed Database.  The Relative Citation Ratio (RCR) is a metric provided NIH that reflects a citation-based measure of scientific influence. Search by author name, title, or MeSH keyword or input a list of PubMed IDs. 

Pros and Cons of Bibliometrics


  • Citation = Impact: If an article is cited, that typically indicates that the work has had some impact on others in the field.
  • Objectivity: Metrics are calculated using equations, reducing the chance of bias that might occur through human judgment.
  • Statistical Analysis: There are many tools available to provide authors with citation data and to perform advanced statistical analyses of that data. 
  • Time-Saving: Relatively easy to implement, methods are straightforward. 


  • Time: Citations take 1-2 years on average to accumulate (Priem, Piwowar & Hemminger, 2012), so newer works may be left out.
  • Impact Level: Citation analysis only works at the author or journal level; cannot measure impact at the article level.
  • Narrow Focus: Focuses on peer-reviewed articles only, leaves out other types of research such as datasets that comprise a large part of the global literature.
  • Language Bias: Article authors are more likely to cite works written in the same language as the article.
