The Journal Citation Reports (JCR) database is a unique and comprehensive tool providing bibliometric analysis of more than 5,900 journals in the areas of science and technology and of 1,700 journals in the social sciences. Coverage is international and includes journals published by over 3,300 publishers in 60 countries.
The aim of the JCR is to provide a systematic and objective means of determining the relative importance of science and social sciences journals within their subject categories.
JCR uses Thomson Reuters Web of Science citation data.
