About Journal Impact

Impact Factor - What is it?; Why use it?

The impact factor (IF) is a measure of the frequency with which the average article in a journal has been cited in a particular year. It is used to measure the importance or rank of a journal by calculating the times it's articles are cited.

How Impact Factor is Calculated?

The calculation is based on a two-year period and involves dividing the number of times articles were cited by the number of articles that are citable.

—Calculation of 2010 IF of a journal:

¢A = the number of times articles published in 2008 and 2009 were cited by indexed journals during 2010.
¢B = the total number of "citable items" published in 2008 and 2009.
A/B = 2010 impact factor
