The new edition of Thomson Reuters (ISI) Journal Citation Reports (JCR) is now available to subscribers of the JCR Web. The recognized authority for evaluating journals, JCR presents quantitative data that supports a systematic, objective review of the world’s leading journals and their impact and influence in the global research community. 

JCR publishes the journal Impact Factors (IFs) on two databases, the Science Edition, and the Social Science Edition. JCR evaluates academic journal quality based on citations received by articles in a given journal by journals in the ISI Web of Knowledge citation index. JCR then assigns each journal an “impact factor” rating, based on the citations received by papers published in the last two years in a given journal.

The JCR summarizes citations from more than 10,000 journals and proceedings in the sciences and social sciences indexed in the Web of Science database. Nearly 8,000 journals appear in the 2007 JCR, with detailed reports of their citation performance, their citation network, and the count and type of materials published.
