Impact Factors and Other Metrics: Author Level Metrics


Author-level metrics are citations metrics that measure the bibliometric impact of individual authors, researchers, academics, and scholars. 

Types of Metrics

H-index - The h-index (or Hirsch index) is based on the impact of a particular scientist rather than a journal. It is measured using the highest number of papers included that have had at least the same number of citations. For example, if the h-index for an author is 8, it means that out all of his published articles, at least 8 have been cited 8 or more times. 

Note: An individual's h-index may be different in various databases. This is because the databases index journals differently. Scopus will cover from 1996+ whereas Web of Science will only cover years subscribed to database. See Author Details to find h-index.
