Indicators of Publication Research Impact: Author Metrics

Metrics to help you demonstrate the scholarly impact of articles, authors, and journals

Author Metrics

How are you performing as an author across all of your publications? How often have you been cited?


An author has an h-index of n when the author has had n papers cited n or more times.

For example, Graham H. Timms was an author on seven medicinal chemistry papers between 1989 and 2006, which were cited 7, 16, 9, 13, 53, 4, and 7 times respectively (data from Web of Science). To calculate the h-index manually, enumerate the articles in descending order of citation count:

Article Number Times Cited
1 53
2 16
3 13
4 9
5 7
6 7
7 4

The last article number (in this case, number 6) which is less than or equal to the corresponding citation count (7) is the author’s h-index. So, Graham H. Timms has an h-index of 6, that is, he has had 6 papers cited 6 or more times.

The h index can be restricted to a specific timeframe simply by only including articles published during that period. This might be appropriate for calculating an h-index for the period since a member of faculty’s previous promotion.


Created for Google Scholar, the i10-index is a count of the number of an author’s publications with at least 10 citations. In the case of Graham H. Timms above, his i10-index would be 3. Google Scholar includes an i10-index metric in its author profile.

Web of Science

Create a Citation Report of your work in Web of Science. This is limited to citations of your work by resources indexed in Web of Science.

Data available include:

  • number of citations received
  • number of articles citing a particular article
  • average number of citations per article in the result set
  • h-index of the result set or author

Additionally, further analysis is possible and the resulting data set can be exported.

Google Scholar

Once you've created a My Citations profile in Google Scholar, simply log in to view your current statistics. Available data include:

  • Citation count
  • h-index
  • i10-index

For example:


Richard Feynman has been cited 82,269 times over his career. He has 59 articles with 59 or more citations and 93 articles with ten or more citations.
