Tools for finding Impact Factors

  • Journal Citation Reports via Web of Knowledge.

This is the key standard for Impact Factor data.  Available at RHUL: http://eresources.rhul.ac.uk/kb/JCR

Download the application from the website – you should be able to install it on your PC.  It uses data from Google Scholar, so it picks up titles not included in JCR, such as reports and other non peer-reviewed materials.  The results are therefore widely different from JCR and should not be directly compared.

Data is still being developed as this service is quite new.  It’s more about the number of author citations than about journal impact factors.

  • Scopus

Good subject coverage, but uses a different way of calculating impact factors from JCR so it is not possible to compare between the two. Available at RHUL: http://eresources.rhul.ac.uk/kb/Scopus

Takes data directly from JCR, but doesn’t usually include the most recent report data.
