Types of Metrics

Web of Science Core Collection and Scopus measure how often an article has been cited (i.e. referenced by another journal article indexed by the database) and gives details of the citing articles.

To keep track of how your own articles you can set up a citation alert (in Web of Science or Scopus). Also both products offer profiling services.

The h-index (or Hirsch index) is a relatively new, but increasingly important, method of assessing the impact of an individual's publications.

The h-index uses a calculation based on the citation rates of an author's published papers. For more information about the h-index see articles in PNAS and Nature.

This is an emerging movement to use a wider range of metrics in addition to traditional citations. This can include discussion (e.g. Twitter), saving (e.g. Mendeley, Delicious) and sometimes viewing or recommending an item.

This can give a better picture of impact, but until this is better understood probably needs to be used with caution.

We have a lot more information on our guide to altmetrics.

Essential Science Indicators

Essential Science Indicators allows you to identify the most highly cited (top 1%) papers in the Web of Science Core Collection. (Note the top 1% is a high threshold - many good papers will fall outside it.) It also includes Field Baselines (expected citation rates for papers in a research field).

Subject Specific Metrics / Citation tools

This is a listing of subject specific databases that track citations or at least offer some analytical functionality.
