What is the h-Index?

"Index h, [is] defined as the number of papers with citation number higher or equal to h" Hirsch, 2005

Where can I find my h-Index?

• Web of Science
• Create a profile in Google Scholar
• Scopus (no subscription at UF)
• Use the Publish or Perish software

Harzing's Publish or Perish software uses Google Scholar to obtain citations from a particular author and calculate these statistics:

• Total number of papers
• Total number of citations
• Averages
• H-Index
• Various off-shoots of the H-Index such as the G-Index

i10-index:  the number of publications with at least 10 citations each. Introduced in 2011 by Google Scholar.

The h-index and m quotient:
