2. h-Index h-index developed in 2005 by Jorge Hirsch, University of California in San Diego Attempts to quantify productivity and apparent scientific impact of a scientist. “A scientist has index h if h of his/her Np papers have at least h citations each, and the other (Np − h) papers have no more than h citations each”. For example, an h-index of 20 means that the researcher has 20 papers each of which has been cited 20 or more times Calculated by Scopus, WoS, Google Scholar, but only for those papers within the database 29/04/2015www.rba.co.uk2
