New! Journal Citation Reports 2004 data

Thomson Scientific just announced that the 2004 data is now available for Journal Citation Reports.

Enhancements include more category level analysis: much of the same statistical information available for individual journals is now available for journal categories, for data from 2003 forward. This provides a view of coverage, citation behavior and relationships across an entire subject. Cited Category and Citing Category lists show the most frequently cited journals in the subject. This information helps put a journal's impact factor into context.
