How to find a Journal Impact Factor

What is a Journal Impact Factor?

An impact factor is a measurement provided by Thomson Reuters looking at the average number of citations articles in a particular journal receives. 

It is calculated by:
The number of times that all items published in a journal in the previous two years (e.g. 2012 & 2013) were cited by indexed publications during the year of interest (e.g. 2014)

divided by

The total number of "citable items" published by that journal in those two years (e.g. 2012 & 2013)

  • Start typing the name of the journal and choose from the list that appears:
