H-Index - Research Impact and Citation Analysis - LibGuides at University of Newcastle Library



Jorge Hirsch proposed the h-index or Hirsch index in 2005 as a means of quantifying the impact and productivity of a scientist. The h-index is calculated on the number and impact of a researcher’s publications.  An h-index of 40 means that a researcher has published 40 papers that each have at least 40 citations. 

Several resources - Web of Science Citation Indexes, Scopus, Google Scholar (via 'Google Scholar Citations' and 'Publish or Perish') and Microsoft Academic Search - include the necessary citation data to calculate a h-index score.

More Information: Hirsch, J. (2005). An index to quantify an individual's scientific research output. PNAS 102 (46): 16569-16572. 

h-index of an author will be different in each of these resources,
since the calculation is based on the indexed content within each

Publish or Perish is a free software program that retrieves and analyzes academic citations. POP uses Google Scholar to obtain the raw citations.

Google Scholar Citations
provide a simple way for authors to keep track of citations to their
articles. You can check who is citing your publications, graph citations
over time, and compute several citation metrics. You can also make your
profile public, so that it may appear in Google Scholar results when
people search for your name, e.g., richard feynman.

Microsoft Academic Search allows authors to create profiles - total citations, G-Index and H-Index are automatically calculated . See which University of Newcastle researchers have  setup Microsoft Academic Search accounts.
