Visit Google Scholar Metrics Help for more information on the metrics provided, coverage and inclusion.
Using data from Google Scholar, the freely available Publish or Perish software can be used to generate a variety of metrics.
Developed by Anne-Wil Harzing, Professor in International Management at the University of Melbourne, the program can be installed without the need for administrative privileges.
Why use Publish or Perish?
SCImago Journal and Country Rank uses Scopus data to compare journals and countries. It is freely available on the web.
Journal h-index is one measure of the quality of a journal and can be calculated using data from Web of Science, Scopus or Google Scholar. As with the impact factor, journal h-index does not take into account differing citation practices of fields (unlike the weighted SJR and SNIP) and so is best used to compare journals within a field.
'An entity has an h-index value of y if the entity has y publications that have all been cited at least y times'.
(Hodge & Lacasse 2011, p. 583)
Flexible publication window
While JCR's impact factor offers calculations based on windows of two and five years, and SJR and SNIP are based on three years, the h-index publication window can be selected to best suit the citation practices of a discipline.
Go to Google Scholar and select Metrics:
The Google Scholar h5-index is based on a five year publication window - 2008-2012. To calculate h-index based on a different range of years use Harzing's Publish or Perish.
