The h-Index is a different type of measure which is assigned to an author rather than a particular paper or work. This is a more recent measure developed in 2005 by Dr Jorge Hirsch, a physicist at the University of California.

The h-index is designed to measure the impact and productivity of a researcher. It examines the total number of papers published by a researcher and the number of citations received by each paper. The h-index is calculated by the number of papers from an individual’s publication list to have at least the same number of citations. If a researcher has a h-index of 5 then they have at least 5 publications with 5 or more citations.

It’s commonly accepted that the h-Index varies for different research disciplines, purely because of the different publishing patterns of the disciplines.
