Measure Your Research Impact-h-index, impact factor and more: h-index

What is the h-index?

The h-index:

  • proposed by JE Hirsch in 2005
  • a tool to measure an author's productivity and impact of published work
  • is based on the researcher's most cited papers and the number of citations that they have received (were these two numbers meet)
  • to calculate:
    • organize articles in descending order (most cited to least cited)
    • see where the two numbers meet, article 6 was cited at least 6 times (see graphic below)

Let's look at Albert's h-index

Calculating Albert's h-index

To calculate Albert's h-index we need to:

  1. Collect all of Albert's pupblications.
  2. Put the publications in order from highest citation count to lowest count.
  3. Determine where the number of publications (h) and the citation counts meet.
    For example:
    Have I published one publication with at least one citation count? Have I published two publications with at least two citation counts? Continue to ask the question until you can't answer yes to the question.

Below are Albert's 8 scientific publications in order by citation count:


Publications      No. of citations

Publication 1      15
Publication 2      12
Publication 3      12
Publication 4        8
Publication 5        7
Publication 6      6
Publication 7        5
Publication 8        4

  1. Albert has a total of 8 publications; 6 publications have at least 6 citations:

Find your h-index in Symplectic?

Anyone with a profile in Symplectic (our publications and more tracking system) can easily find their h-index.

  • First make sure that all of your journal publications that can be found in PubMed, Scopus and Web of Science are claimed in your profile.
  • Go the the Home tab and look in the first column for the My h-index box. You will see the h-index reported in three databases:
    • Scopus
    • Web of Science (this is the number our institution uses)
    • Europe PMC

How can I find my h-index one database at a time?


  1. Click on the link above and logon to UC.

  2. In Scopus, click on the Author search tab. Enter the author's last name, first name or initials and click on the search icon.

  3. Check the boxes next to the names that match the author that you need and click Show documents.

    Make sure that all of the articles listed are the correct and check the boxes.

    If all the articles are correct check the Select all box and click on View Citation overview.

  4. The h-index can be found to the right of the citations.

Web of Science:

  1. Click on the link above and logon to UC.

  2. In Web of Science Enter the name of the author in the top search box (e.g.. Smith JT). Select Author from the drop-down menu on the right. Click Search.

  3. Check the results to make sure all of the articles listed are correct. Check the boxes of the correct articles or choose or skip to step 4 if all are correct.

  4. Click on Citation Report on the right hand corner of the results page, the h-index is located on the right side of the screen.

Google Scholar:

You can see your h-index in Google (using your gmail) account by creating a profile of all your articles found in Google Scholar. You will also be able to see how many times the articles have been cited by other documents in Google Scholar. You make your profile public or private.

To get an idea of what it looks like here is Albert Einstein's h-index.

*Please note that databases like Scopus and Web of Science include the h-index but do not index every journal. Depending on the discipline you may be better off using one database over the other.
