Calculate your controversial 🙂 h-index:

Calculate your h-index (Hirsch index) in Google Scholar 

What is the h-index?

 e.g. a h-index of 20 means the researcher has 20 papers each of which has been cited 20+ times.


An alternative to total citations which can be disproportionately affected by a few very highly cited papers.

Where to start:

With Google Scholar there are a variety of sites and programs that can help you calculate your h-index. These

are generally free and quality varies.

Recommended sites and services:

1. Citations Gadget for Google Scholar – adds a search

box to an iGoogle page, not browser specific and needs a Google account.

– adds metrics to the standard Google Scholar site. Easy to use and available for Mozilla Firefox(version 3+ of the add-on recommended with a recent version of Firefox) and Google Chrome.

– add-on for the Mozilla Firefox and Google Chrome browsers appears as a sidebar when installed.

4. Publish or Perish

– application (Windows/Mac/Linux) that calculates a wide variety of metrics.

5. My Citations

including the h-index. The profile can be public or private.

How to search

o -authoring with WR Nichols)

o It is possible

These are useful to eliminate namesakes

o Once you are satisfied you may want to make a note of how you searched. This will save time if youneed to repeat the process.

The results screen should show your h-index, and possibly other metrics.

use, all can do this except 2).

Using Google Scholar for the h-index



o Covers a wider range of sources,(especially conferences, technical reports and eprints).

o Easier to calculate some of the less proprietary data thus more innovation)

o Free


o May be considered a less authoritative than Web of Science

o More difficult to search where there are multiple authors with the same family name & initials limited options to refine

Issues to be aware of:

o In general you can only compare values within a single discipline. Different citation patterns will mean for example an average medical researcher will generally have much larger h-index values than a world-class mathematician!

o Also if you are comparing people all h-index values need to be found using the same database, and using the same method.

o The h-index may be less useful in some disciplines, particularly some areas of the humanities.

More details

o References to articles in the scientific literature.

o Calculating the h-index with different databases (e.g. Web of Science).

o Other bibliometrics including variations on the h-index.
