The Journal Citation Reports allows you to evaluate and compare journals using citation data drawn from approximately 12,000 scholarly and technical journals and conference proceedings from more than 3,300 publishers in over 60 countries/territories. JCR includes virtually all specialties in the areas of science, technology, and social sciences. (Contains the Science Edition and the Social Science Edition)
The basis for the quantitative information is the relationship between citing and cited journals. JCR calculates, among other things, the so-called Impact Factor of a journal.
