Measuring your impact: bibliometrics

Research funders, third level institutions and prospective employers increasingly evaluate research outputs using measures which include quantative indicators such as bibliometrics. Bibliometrics look at publication profiles and citation analyses, which are important grant and career measures for individual researchers. There are various tools available to generate bibliometric analyses and which enable authors to optimise their own profile.

Scopus database

Scopus is a major abstract and citation database which indexes research output in the fields of science, technology, medicine, social sciences and arts and humanities.

Scopus has over 60 million records, covering 21,500 peer-reviewed journals. Coverage of books, book chapters and conference proceedings continues to increase. There is strong coverage of pharmacology, European journals and patents.

In addition to being a resource to search for articles and other items, it is also extensively used to evaluate research. Your outputs (articles, conference papers, book chapters) are automatically gathered under a Scopus profile with a unique author identifier. Analyses such as h-index, number of citations, documents by type / source / year etc. can be displayed and downloaded to spreadsheets.

Find Scopus on the Library's Databases page.

Web of Science (WOS)

Web of Science is a large suite of multidisciplinary databases which include many years of citation data. WoS Core Collection indexes 12,000+ journals and citation analyses can be generated with ranking by author output and total citation count in addition to metrics such as h-index. Institutions and individual journals may be ranked by outputs and impact factors.

Google Scholar

Google Scholar and Google Scholar Citations offer researchers another way to collate and present their work. The freeware application Publish or Perish can be used to analyse Google Scholar metrics and to download all citations.


Altmetrics complement traditional bibliometrics by tracking the early impact of your research outputs. They uncover conversations occurring on twitter, blogs, websites, academic networks, reference management systems, and other social media forums. They can be an indicator of influence and data gathered can show how research may change practice. is an example of an organisation involved in this area. Scopus now includes altmetrics at article level, as do many individual journals and publishers.


Irish research libraries have produced an excellent bibliometrics tutorial called  MyRI (My Research Impact). The tutorial and supporting learning resources examine the main bibliometric tools in detail, show you how to track your research impact and outline journal citation and ranking methods.
