Finding and Comparing Journal Impact Factors in Web of Science
The impact factor of an academic journal helps you determine the importance of a journal within its field. This number is calculated by dividing the number of current year citations to the source items published in that journal during the previous two years.
Web of Science's Journal Citation Reports allows you to search for the impact factor of specific journals and compare impact factors across all journals in your field of study.
Search for a journal by its title or ISSN from the homepage. The journal profile will include its Journal Impact Factor, some its top cited articles, and more.
You can also compare the Journal Impact Factor of journals in a particular field.
1. One the JCR homepage, click on the Categories button.
2. Click on a category group and sub-category. You will have the option to choose the Science Citation Index-Expanded (SCIE) or Emerging Sources Citation Index (ESCI) list.
3. Then, you'll see a list of all journals in that category ranked by Journal Impact Factor.
