How do I find journal impact factors?

You can find impact factors in the Web of Science database. Look for "Journal Citation Reports" along the ribbon at the top of the page.

Web of Science also includes Cited Reference Search, which shows how often a certain article has been cited.

For metrics on how many times an article has been downloaded by readers, see our FAQ answer on "usage factors."

For further information on journal metrics of all kinds, see this helpful guide maintained by Johns Hopkins.
