Impact Factor

INTRODUCTION:
The impact factor   is a measure of the frequency with which the "average article" in a journal has been cited in a given period of time.. It   is   also abbreviated as IF. The   journals with higher impact factors are of more importance than the lower ones. The impact factor was devised by Eugene Garfield, the founder of the Institute for Scientific Information (ISI), now part of Thomson Reuters.

The impact factor for a journal is calculated based on a three-year period, and can be considered to be the average number of times published papers are cited up to two years after publication.
Calculation of impact factor in 2009
Cites in 2009 to articles published in:
2008 = 556
2007 = 568
Sum = 1124

Number of articles published in:
2008 = 103
2007 = 109
Sum = 212

Cites to recent articles (1124)
Number of recent articles (212) = 5.302
