1. To find a journal's Impact Factor (IF): 

A. Search journal title in the main search box;

B. Under "Journal Impact Factor" you can find IF of the past five years. 

2. To find out journal IF rankings of a specific subject:  

A. Click “Browse by Journal”, then Switch to "Categories by Rank" on the top of the page; 

B. Select the subject you are interested in searching. (If you cannot find the subject, click on the "Category" tab on top of the table to switch to the alphabetical order) 

Google Scholar Metrics is an alternative tool in case you could not find the journal in JCR. This is Google's ranking of publications using the Google Scholar index. Here you can check a journal's H5 Index and H5 Median instead of IF.  

(Note: Here you can search by journal title for the H5 index and you may be able to find it, it may not list the ranking within a category as currently Google Scholar Metrics only ranks the top 20 in each category.)

For more help, ask a librarian.
