Research Impact: Citation Impact

Tools and support to assist with measuring research.


Subject specific databases

Search a range of databases that provide citation counts since Web of Science and Scopus do not cover all disciplines well. There are a number of databases that can help you to count citations. However, they will not provide tools to analyse citations.

Media Mentions

While you may remember your appearances on TV your work may also have been discussed in newspapers.

Tips and Tutorials


Keep track of your process of counting citations. For example, record the databases you used, and whether you included or removed self-citations.

In Web of Science you may get two citation counts. Times cited count refers to content from Web of Science only. Cited by count includes citations also from the Web of Knowledge.

In Web of Science use the name of the first author of an article since secondary authors are not always found in the Cited Reference searches.



No citation tool will provide a complete citation count. Variations occur because citation tools have different source materials, date ranges and sometimes erroneous records.

See below an example of distribution of citations of a book
 in Bar-Ilan, J. (2010) Citations to the “Introduction to informetrics” indexed by WOS, Scopus and Google Scholar. Scientometrics, 82(3), p.504.

Distribution of citation between Web of Science, Scopus and Google Scholar

Note also that citation counts are not comparable across disciplines. For example, citation counts in Social Sciences and Humanities are lower because researchers are more often publishing in books and conference papers that are not well covered by citation databases.
