Journal Citation Reports

Within the Web of Science database, you can select Journal Citation Reports and view the journal impact factor from ‘journals by rank’.



By default, journals are sorted by their impact factor, regardless of category. The higher the impact factor, the more highly ranked the journal is. For example, an impact factor of 1.0 means that on average the articles published one or two years ago have been cited only once.



When searching for a particular journal or multiple journals within the same category, use the filters on the left refine your search. Avoid using the “Categories by rank” tab, as it only provides you information about the category as a whole. Instead, search for the category with the “Select Categories” menu.

When searching for articles, you can sort the articles based on the number of times they have been cited by others. This can help you to find out the frequency of citations made on the article.

For example, let’s key in the search terms paediatrics” and “asthma” in the boxes provided on the basic search page.


By default, results will be listed by their publication date. Change this to “Times Cited — highest to lowest” from the drop down menu.



On the right side of the panel, you can view the number of times the article has been cited. Do note that these numbers only include citations from articles hosted by Web of Science.
