Citation analysis tool – Publish or Perish

This is one of a series of posts describing tools that are available for citation analysis.  For other tools see here.

Harzing’s Publish or Perish (PoP) “is a software program that retrieves and analyzes academic citations. It uses Google Scholar to obtain the raw citations, then analyzes these and calculates a series of citation metrics.” (Publish or Perish User’s Manual, 2012)

The tool is particularly recommended for citation analysis in the Social Sciences, Arts, Humanities and Engineering, all of which subjects may be more extensively covered in Google Scholar than in Web of Science (Harzing, 2012).

To use Publish or Perish:

  • To use PoP you must first download and install the software; it is free for personal, non-profit use.
  • Once installed, the program can be run by clicking ‘Start’, then ‘All programs’, then ‘Publish or Perish 3’

Citation analysis using Publish or Perish – Author impact:

  • Launch PoP (as above)
  • Click on the ‘Author impact’ tab
  • Enter the author’s surname and initials (typing quotation marks around these will give a more accurate result)
  • Optionally, enter author names to exclude, a date range and select subject areas
  • Click on ‘Lookup’

Citation analysis using Publish or Perish – Journal impact:

  • Launch PoP (as above)
  • Click on the ‘Journal impact’ tab
  • Enter the journal name (again, typing the name in quotation marks will restrict the results to the specific name entered)
  • Optionally, enter journal names to exclude, a date range and select subject areas
  • Click on ‘Lookup’

Citation analysis using Publish or Perish – General citations:

This is equivalent to performing an Advanced Search in Google Scholar and analysing the results.

  • Launch PoP (as above)
  • Click on the ‘General citations’ tab
  • Enter the required field(s)
  • Optionally enter a date range and select subject areas
  • Click on ‘Lookup’

Making sense of the results:

Each of the above searches will produce a list of papers and citation statistics based on the results of a query passed to Google Scholar.  The next step is to refine the list so it includes only papers that rightfully belong to the author or journal of interest.

The simplest refinement is to remove some of the subject areas or restrict the date range.  If performing a journal search, then sorting by Publication (click on ‘Publication’ in the results table header) is useful.

Finally, you should go through the list, checking every item that belongs to the author or journal being assessed. This will determine the exact records used in the calculation of citation statistics.

PoP offers a range of citation metrics, including the following:

  • Total number of papers
  • Total number of citations
  • Average number of citations per paper
  • Average number of citations per author
  • Average number of papers per author
  • Hirsch’s h-index and related parameters
  • Egghe’s g-index
  • The contemporary h-index
  • Three further variations of the individual h-index
  • The age-weighted citation rate
  • An analysis of the number of authors per paper.

The PoP User’s manual provides further information on these.
