Impact Factor & Ranking

The Journal Impact Factor is defined as all citations to the journal in the current JCR year to items published in the previous two years, divided by the total number of scholarly items (these comprise articles, reviews, and proceedings papers) published in the journal in the previous two years.
Though not a strict mathematical average, the Journal Impact Factor provides a functional approximation of the mean citation rate per citable item. The citing works may be articles published in the same journal.  However, most citing works are from different journals, proceedings, or books indexed in Web of Science Core Collection.

5-Year Impact Factor

The 5-year journal Impact Factor, available from 2007 onward, is the average number of times articles from the journal published in the past five years have been cited in the JCR year. It is calculated by dividing the number of citations in the JCR year by the total number of articles published in the five previous years.
