Q. How can I find a journal's impact factor?

A free resource that you can use to find information to help determine a journal's influence/quality is Scimago Journal & Country Rank.

You can also use the UMGC Library's Scopus database to find a journal's CiteScore, which is a measure of the journal's impact.

Scopus can also be used to compare two or more journals on a variety of parameters (number of cited articles, number of published articles, etc.). See the Scopus Browsing and analyzing journals tutorial for more information.
