Course Research Impacts: Finding articles of an author

Finding articles of an author

The Advanced Scholar Search in Google Scholar has the option to search by Author. You can enter the authors name behind Return articles authored by. This is often not very specific, it's hard to limit the results for a specific author. 

However, there is software available, based on Google Scholar data, which offers more options for author searches: Publish or Perish. This software can also compute metrics, like the H-index, based on Google Scholar.

Another option to search for particular authors is to use the Google Scholar Citations profiles of these authors. Authors have to create and update this profile themselves, so not every researcher is available in Google Scholar like this.

In this part of the course we cover:

  • Publish or Perish
  • Author search in PoP
  • The H-index in Publish or Perish
  • Google Scholar Citations Profiles
  • The H-index in Google Scholar Citations

About Publish or Perish

Publish or Perish (PoP) is a free software program, which uses data from Google Scholar (among others) to retrieve and analyze academic citations. You can download PoP from the website of Anne-Wil Harzing, professor in International Management at the Middlesex University, London and the creator of PoP: https://www.harzing.com/pop.htm.

Want to know more? Look at this presentation of Anne-Wil Harzing.

In this course we will cover some of the basics of PoP, in the Publish or Perish Book and the Publish or Perish Tutorial you can find more details.

Author search in Publish or Perish

After downloading and installing the PoP software on your computer you can search for publications of an author in Google Scholar.

When the query screen is empty, select Google Scholar. Enter the name of the author(s) behind Authors (initials last name, for example D Ariely). Click the button Search to start the search.

The results consist of the list of publications, including the number of citations received, and the citation metrics, based on the list of publications.

Publish or Perish search results

In most cases you’ll have to narrow down the search results before you can use the citation metrics, because publications of other researchers can be in the list.

  • Check for example the years of publication - do they make sense?
  • Sort by the publication (often the journal) - this can help to find publications in journals outside the discipline of your target researcher.
  • If you see author names in the list that you want to exclude, you can use the - sign in the Authors field (for example A Nieboer -KA Nieboer -NA Nieboer)
  • You can unmark publications in the list that don’t belong to the target researcher.

Please note: Google Scholar allows a maximum of 1000 publications. When there are more results, you’ll see an error message in Publish or Perish. You can narrow your search for example by choosing specific publication years.

When you know that the author you are looking for has a Google Scholar Profile, you can also search for a profile. Select Google Scholar Profile in the start screen and enter the name and optionally the affiliation of the author you are looking for.

The H-index in Publish or Perish

In the Metrics box you’ll see the following citation metrics:

  • Publication years
  • Number of citation years
  • Number of (marked) papers in the list
  • Number of citations received by the publications in the list
  • Average number of citations per year
  • Average number of citations per paper
  • Average number of citations per author: the number of citations per paper is divided by the number of authors for that paper. These numbers are added up.
  • Average number of papers per author: for each publication 1 is divided by the number of authors. These fractional author counts are added up.
  • Average number of authors per paper
  • h-index
  • g-index: proposed by Egghe: the largest number such that the top g articles recieved (together) at least g2 citations. (A g-index of 10 means that the top 10 of the most cited papers combined have at least 100 (10*10) citations.) It gives more weight to highly-cited articles in comparison with the h-index.
  • hI,norm: Normalized individual h-index. The number of citations for each publication is normalized, by dividing the number of citations by the number of authors for that publication. Then Hi,norm is calculated as the h-index for the normalized citation counts.
  • hI,annual: Annualized individual h-index. This metric addresses the problem of comparing academics at different career stages. It is calculated as follows: hI,norm/academic age, where academic age = number of years elapsed since first publication
  • *Count: The number of results whose cites/year metric equals or exceeds the "star" threshold set in the Tools > Preferences > Results settings in Publish or Perish.

You can export these metrics to Excel:

  • Open an empty Excel sheet
  • Click the button Copy Results under the results and choose Metrics for Excel with Header
  • Go to Excel and use Paste

You can also export the list of results: choose Results for Excel with Header.

Google Scholar Citations Profile

In the search results in Google Scholar, author names are underlined when the author has a Google Scholar Citations profile.

Google Scholar example authors underlined

The profile shows the publications added by the researcher to his or her profile and the citations to these publications within Google Scholar.

Example Google Scholar Citations Profile

When you click a title in the profile, you can see more information about the publication (for example the abstract), and the citation graph for that publication.

The H-index in Google Scholar Citations Profile

The Google Scholar Citations profile shows three metrics, based on all publications added to the profile and all citations for these publications and based on the citations received in the last 5 year:

  • the total number of citations
  • the h-index
  • the i10-index - the number of publications that have received at least 10 citations. In the second column you see the number of publications that have received at least 10 new citations in the last 5 years.
