The use of journal metrics to evaluate faculty performance has pros and cons, especially depending on your discipline. Note the Subject Coverage in the boxes below.
Major journal metrics currently available, along with their definitions, are:
Remember that journal metrics are based on differing citation counts and may be calculated differently from one resource to the next. This means, for example, that the journal h-indices from Google Scholar and SCImago are not interchangeable or comparable. See the rest of this page for details on how to find the various journal metrics.
JCR is based on the same journal list as Web of Science, which is considered the "gold standard" in databases. JCR tracks citations to more than 12,800 titles, the majority of which are in the science disciplines.
Subject coverage. 65% Sciences, 23% Social Sciences, and 13% Arts and Humanities.
Publication types. Peer-reviewed journal articles and some technical/trade journals.
Limitations. 1) Weak coverage of humanities and social sciences; and 2) trade and practitioner journals are generally not included.
