How do I find the impact factor of a journal?

To find out which are the leading journals in a field (i.e., those with the highest “impact factors” whose articles are cited most frequently), look in Journal Citation Reports (JCR). The impact factor will help you evaluate a journal’s relative importance, especially when you compare it to others in the same field.

In JCR you can select the Science or Social Sciences editions and then search for a specific journal or view journals by subject category, publisher or country. The Information for New Users provides good online help.
