Your h-index Print Page


  • In 2005, physicist Jorge E. Hirsch developed the h-index as a process for quantifying the output of an individual researcher.
  • Hirsch argues: “I propose the index h, defined as the number of papers with citation number ≤ h, as a useful index to calculate the scientific output of a researcher” (2005).
  • Note that the h-index is one of many available bibliometric measures.

Key Tools

  • Given Scopus and Web of Science's citation-tracking functionality, they also calculate an individual’s h-index based on content in a particular database.
  • Likewise, Google Scholar collects citations and calculates an author's h-index via the Google Scholar Citations Profile feature. 
  • Note that each database may determine a different h-index for the same individual as the content in each database is unique and different. 


Known limitations of the h-index are explored by these publications:

Calculate Your h-index

  • To manually calculate your h-index, organize articles in descending order, based on the number of times they have been cited (see below example).

  • Web of Science, Scopus, and Google Scholar can also be used to calculate an h-index for that particular citation-tracking database.


In the below example, an author has 8 papers that have been cited 33, 30, 20, 15, 7, 6, 5 and 4 times. This tells us that the author's h-index is 6.

h-index calculation

What does an h-index of 6 mean?

  • An h-index of 6 means that this author has published at least 6 papers that have each received at least 6 citations.

More context:

  • The first paper has been cited 33 times, and gives us a 1 (there is one paper that has been cited at least once).
  • The second paper has been cited 30 times, and gives us a 2 (there are two papers that have been cited at least twice).
  • The third paper gives us a 3 and all the way up to 6 with the sixth highest paper.
  • The final two papers have no effect in this case as they have been cited less than six times (Ireland, MacDonald & Stirling, 2013).
