Looking for journal impact factors? Don’t know where to find them?

The TMC Library can help you.

Journal Citation Reports (JCR) is a comprehensive database of comparative journal metrics for over 8,000 scholarly and professional journals in 227 disciplines from more than 3,300 publishers. The TMC Library has a subscription to JCR for the Science and Social Science editions.

JCR ranks journals within various disciplines arriving at an “impact factor” based on data like frequency of citation, number of articles published annually, and “cited half-life.”  Citation and article counts indicate how heavily current researchers are using particular titles in a field, and may indicate the quality of a title. By tabulating and aggregating this data, JCR offers a unique set of standards for journal evaluation and comparison.

When you access JCR you can:

  • View a group of journals by Subject Category, Publisher, or Country/Territory. The default option is Subject Category
  • Search for a specific journal title
  • View all journals in the current JCR edition, or view retrospective data back to 2000.

 To access JCR, go to the Library website, click on the databases link on the left side of the page, and choose the letter J.  Click on JCR (Journal Citation Reports), the first link in the middle of the page.
