The h index was proposed by J.E. Hirsch in 2005 and published in the Proceedings of the National Academy of Sciences of the United States of America. The h index is a quantitative metric based on analysis of publication data using publications and citations to provide “an estimate of the importance, significance, and broad impact of a scientist’s cumulative research contributions.”

The H-Index is a popular tool for determining relative impact of an author's work by qualifying an author's cited publications.

Calculating: A researcher (or a set of papers) has an h-index of N if he/she has published N papers that have N or more citations each. The h-index is based on Times Cited data from the database.

An h-index is a rough summary measure of a researcher’s productivity and impact.Productivity is quantified by the number of papers, and impact by the number of citations the researchers' publications have received. The h-index is an author-level metric that measures both the productivity and citation impact of the publications of a scientist or scholar. The h-index correlates with obvious success indicators such as winning the Nobel Prize, being accepted for research fellowships and holding positions at top universities. The H-index is displayed in the "Cited by" box on the right hand of your profile page. Also displayed are the total number of citations that all of the articles in your profile have received, and the "i10-index", which shows how many of your articles have received at least 10 citations.

The index is based on a list of publications ranked in descending order by the number of citations these publications received.
