Journal metrics represent the importance of a journal in a discipline based on citations to the journal as a whole over a period of time. 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.
Enter the freely available Journal Metrics module in Scopus. The short videos below demonstrates how to locate CiteScore metrics and Source Normalized Impact per Paper (SNIP):
The database content includes about twice as many journal titles than Web of Science, the majority of which are science journals.
Enter the publicly available SCImago Journal and Country Rank (SCImago). Watch this short video on how to locate the SCImago Journal Rank (SJR) for a title, SJR quartiles, and the h-index:
SCImago is developed from the information in the Scopus database from Elsevier. Therefore, it has the same limitations as Scopus - see the details in the box above.
