Bibliometrics is a set of methods to quantitatively analyze academic literature.  The resources below are free resources.  Others include: 

  • Journal Citation Reports (which evaluates and compares journals based on impact factor, immediacy index, and cited half-life)
  • Scopus (which is a comprehensive citation database that allows users to track citations by a particular author, measure journal performance, and see citation trends in a particular field), and
  • Web of Science (a comprehensive and multidisciplinary citation database that allows users to follow the path of influence by mapping cited references).

If you have privileges at Stony Brook, you can access Journal Citation Reports and Web of Science from its library's website.

  • CiteFactor
    This is one year behind but it is a free resource.
