Journal Citation Reports (JCR) is part of the database Web of Science. JCR has the impact factors for journals in your discipline, and is a great place to determine where to publish your research for the highest impact. Sure, you can google a journal name + the term impact factor to find impact factors quickly, but to get the correct and up to date impact factor, going to the source is best.
Here's how to find JCR & Web of Science on the Matas homepage.
1. Select RESOURCES (top middle-right of screen)
2. Select WEB OF SCIENCE (center middle of screen)
3. Select JOURNAL CITATION REPORTS (upper left corner of screen)
4. Search by journal name or browse by discipline
