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

g-Index
g-index - distribution of citations received by a given researcher's publications
Devised by Leo Egghe in 2006
“Given a set of articles ranked in decreasing order of the number of citations that they received, the g-index is the (unique) largest number such that the top g articles received (together) at least g2 citations.”
