Journal Citation Reports (JCR)
Journal Citation Reports (JCR) allows you to evaluate and compare journals using citation data drawn from over 11,000 scholarly and technical journals from more than 3,300 publishers in over 80 countries. It is the only source of citation data on journals and includes virtually all areas of science, technology, and social sciences.
JCR is published annually around late June or early July (e.g. 2012 data will be released June/July 2013).
