Abstract

The h index Is a bibliometric indicator that evaluates an author-level
metric and attempts to measure both the productivity and citation impact of the
publications of a scientist or scholar. The index is based on the set of the
scientist's most cited papers and the number of citations received in other
publications. The index can also be applied to the productivity and impact of an
academic journal as well as a group of scientists, such as a department or
university or country.[2] The index was suggested in 2005 by Jorge E. Hirsch, a
physicist at UC San Diego, as a tool for determining theoretical physicists'
relative quality[3] and it is sometimes called the Hirsch index or Hirsch number
Therefore, this study aims to identify this index and to determine the most
important advantages, disadvantages, and the most important revisions
