The h-index, introduced in 2005 by the American physicist Jorge Hirsch, measures the productivity of an individual scientist, group or institution. It is an alternative to total citations, which can be disproportionately effected by a few very highly cited papers.

An h-index of 25 means an author has written 25 papers that have each received at least 25 citations.
