J. E. Hirsch, a physicist at the University of California, proposed the h-index to quantify individuals' scientific research output in a 2005 PNAS paper. The h-index measures both productivity and citation impact.
To calculate your h-index, list your papers based on the number of their citations, from most to least. The number of citations for each paper must be equal to or greater than its rank in order to be counted. Thus, if your first paper has at least 1 citation, your h index is at least one. If your second paper has at least two citations, your h-index is at least two, and so on. If you have papers A, B, C, D, and E, with 68, 12, 10, 3, and 2, respectively, your h-index is 3, because paper D (your fourth paper) must have more than four citations to be counted.
1. To find a researcher's h-index with Google Scholar, search for their name.
2. If a user profile comes up* with the correct name, discipline, and institution, click on that.
3. The h-index will be displayed for that author under "citation indices" on the top right-hand side.
* If no user profile comes up, you'll need to use another tool, like Web of Science (below) or manually calculate the individual's h-index.
It's always best to use the h-index in context, comparing scholars with their peers, and using other metrics as well.
