The effect aspect (IF) of any publication is a evaluate showing the common variety of details to recent content released in the publication. It is frequently used as a proxies for the comparative significance of a publication within its field, with journals with higher effect aspects considered to be more important than those with lower ones. The effect aspect was developed by Eugene Garfield, the creator of the Institution for Medical Information.

In any given season, the effect aspect of a publication is the common variety of details obtained per paper released in that publication during the two previous decades. For example, if a publication has an effect aspect of 3 in 2008, then its documents released in 2006 and 2007 obtained 3 details each on regular in 2008. The 2008 effect aspect of a publication would be measured as follows:
A = how frequently that content released in that publication in 2006 and 2007, were mentioned by content in listed journals during 2008.
B = the depend of "citable items" released by that publication in 2006 and 2007. ("Citable items" are usually content, reviews, procedures, or notes; not editorials or characters to the manager.)
2008 effect aspect = A/B.
