Calculating Impact Factors

WHAT IS AN IMPACT FACTOR?
The journal impact factor is a measure of the frequency with which the average article in a journal has been cited in a particular year. The impact factor helps you evaluate a journal's relative importance, especially when you compare it to others in the same field. The impact factor is calculated by dividing the number of citations in the current year to articles published in the two previous years by the total number of articles published in the two previous years.

Using Journal X as an example:
Cites in 2007 to articles published in:	2006 2005 Sum	= 1266 = 1643 = 2909

Number of articles published in:	2006 2005 Sum	= 352 = 364 = 716

Calculation:	Total cites to articles published in 2005 and 2006	2909	= 4.063
	Number of articles published in 2005 and 2006	716

The 2007 Impact Factor for Journal X is 4.063
