Journal Citation Reports (JCR)Journal Citation Reports (JCR) is a subscription database from the makers of Web of Science, the Institute for Scientific Information (ISI). The JCR provides rankings for journals included in the Web of Science database and includes journals in science and social science areas, and to a lesser degree in Arts & Humanities. It includes quantitative measures for ranking, evaluating, categorizing, and comparing journals, including the journal impact factor, a measurement of a journal's importance to a field calculated by citation rates. The University of Connecticut subscribes to this database.
