The H Index“I propose the index h, defined as the number of papers with
citation number ≤ h, as a useful index to calculate the scientific
output of a researcher” .1
“A scientist has index h if h of [his/her] Np papers have at least h
citations each, and the other (Np − h) papers have at most h
citations each.”2

Academy of Sciences of the United States of America, 102(46), 16569-16572. doi:10.1073/pnas.0507655102

Subject Guides. Illinois, Chicago: University of Illinois at Chicago; 2015.
H – Index Example
If an author has 15 papers cited 15 times his or her h-index would be 15. Publications with less than 15 citations do not contribute to the h-index of the author.
Limitations of h-index• Can be influenced by self-citations• Does not account for first authors • Looks at quantity versus influence• Dependent on career length• All types of citations are weighted the same:
reviews, books, primary research, etc. • Dependent on the size of the field• H-index for an author varies when calculated by
different resources
Journal Impact Factor“A journal's impact factor is based on 2 elements: the numerator, which is the number of citations in the current year to items published in the previous 2 years, and the denominator, which is the number of substantive articles and reviews published in the same 2 years.”1

Limitations of the Impact Factor
• Citations to non- source items may inflate the Impact factor
• Self-citation• Journal impact factor varies when calculated by
different resources• Publishing time penalizes disciplines with longer
turnover times• Review articles heavily cited
