The journal Impact Factor is an index that measures how often a journal's articles are cited in other research. This is calculated by the number of citations received by articles published in that journal during the two preceding years, divided by the total number of articles published in that journal during the two preceding years. You can find the journal Impact Factor on the journal homepage.

How

Follow these steps to find the Impact Factor of a journal:

1. Go to the journal's homepage.
2. When you're on the journal homepage, you will be able to see the Impact factor to the right of the Journal's name.

   

For more information on journal metrics, please visit the Measuring a journal's impact page from our website.

If there is no Impact Factor available for your journal, it's likely that it's new within the last 2 years and so the data aren't available yet

To determine if this is the case for your journal, you can find out how long a journal has been publishing for on ScienceDirect:

1. Go to ScienceDirect.com
2. Start typing the name of the journal into the search field ‘Journal/book title’, as you start typing titles will be suggested. When the title of your journal appears, click on it then click the magnifying glass to search.
3. On the search results page, click the title of the journal.
4. You are now on the journal’s publication page, where you can see its previous Volumes listed on the left-hand page. Check the dates against these volumes to determine the journal’s years of publication.
