Journal Rankings & Impact Factors
Impact factor is a measure of the relative importance of a journal. Impact factors give a quantitative measure of a journal’s influence and impact compared to other journals.
For a 2008 journal, the Impact Factor (IF) = A/B
A = the number of times articles published in 2006-7 were cited in indexed journals during 2008
B = the number of articles, reviews, proceedings or notes published in 2006-7
So, a 2008 journal with an Impact Factor (IF) of 3.333 means that on average, each of its 2006 and 2007 articles was cited 3.333 times in 2008.

Author Impact Factor: h-Index
The h-index assesses scientific productivity of a scientist, group, or institution via quantity (# papers) and quality (# citations). In other words, the index is based on a balance between the scientist's most-cited papers and the number of citations per publication.
An h-Index of 25 means that the author has 25 publications that have received at least 25 citations.
An h-index can be obtained from:
