Impact of Research and Scholarly Works: h-Index (Researcher Impact)

Research the impact of a journal, article, individual, or group using a variety of metrics.

What is h-Index?

h-Index measures the influence of an author by counting the number of publications by an author and the number of times they are cited.  h-index was proposed in 2005 by J. E. Hirsch, and is calculated this way:  "A scientist has index h if h of his or her Np papers have at least h citations each and the other (Np - h) papers have <h citations each" (Hirsch, 2005, p. 16569).  Thus a scholar with an h-index of 5 had published 5 papers, each of which has been cited by others at least 5 times.

h-index always uses the above formula, but different results will always happen because the sources that apply the formula have a different data set. So because Web of Science indexes data different from Google Scholar they are always going to be different numbers.

Find h-Index with Web of Science

Find the h-index of a researcher.  Note, the h-index you see may vary depending on what Web of Science databases you are searching in, and the subscriptions your institution has that are indexed in Web of Science.  

First, conduct an author search (Last name, First initial) (you can also choose to select an author from the index):

Author search in Web of Science

Second, click on the "Create Citation Report" link on the right-hand side of the results page:

Finally, you will get a report with a number of metrics and data on the author you searched, including the h-index.

Find h-Index with Google Scholar

For researchers with public author profiles here, you can find an h-Index.  Results with hyperlinked (underlined) author names allow you to click on the name, and see the the author's profile.

Metrics including citations and h-index for the author will appear on the right side of the page.
