Thomson Reuters’ Journal Citation Reports® provides a means for evaluating leading journals with statistical information based on citation data. By gathering articles' cited references, JCR helps measure research influence and impact in both the journal and category levels, and illustrates the relationship between citing and cited journals.
The JCR covers more than 11,000 journals from over 3,300 publishers in approximately 230 disciplines from 80 countries. There are two editions: The Sciences Edition, covering over 8,000 journals; the Social Sciences Edition, coving over 2,600. The Sawyer Library provides access to only the Social Sciences Edition.
