You can look up the impact factor of a journal through the Journal Citation Reports (JCR) database. A journal's impact factor is a measure of how often the average article in a journal has been cited in a particular year. The impact factor will help you evaluate a journal's relative importance, especially when you compare it to others in the same field. Not every journal will have an impact factor, but there are other ways to measure impact to a field.
In Journal Citation Reports, enter the title of the journal or browse journals by rank or category.

Clicking on a journal title will give additional details about the calculation. For example, here is an explanation of how impact factor was calculated for the journal Social Work Research.

Use the "All Years" tab to access key metrics and additional data for the current year and all prior years for this journal.

Since impact factors vary widely by discipline, it is helpful to get a baseline for your discipline by searching for subject area (category). Impact factor data is only available for journals indexed by Web of Science.
