Measuring research impact

Find bibliometric data

The main tools that collect and analyse citation data are:

  • Web of Science
  • Scopus
  • SciVal
  • Journal Citation Reports.

There are some important things to be aware of when you use bibliometric data tools:

  • the coverage of publications is different in each database so you need to use more than one database
  • if you search for author metrics you need to include all possible variations of the author names.

Web of Science

Web of Science is a citation database. It covers science, social science, arts and humanities, dating back to 1900.

Metrics covered include: scholarly output, citation counts and the h-index.

Scopus

Scopus is a citation database. Engineering and social sciences coverage is broader than Web of Science, but citation data is only available for papers published from 1996 onwards.

Metrics covered include: scholarly output, citation counts, the h-index, SCImago Journal Rank and Scopus SNIP.

You can benchmark individual researchers, groups of researchers and institutions with a variety of bibliometric measures.

You need to register for a free Elsevier account to log in to the resource.
