new metrics, new features, new perspectives

For the first time in the Journal Citation Reports’ 30-year history, Thomson Reuters released a mid-cycle version of this infamous product, complete with new metrics and functionality. Our intent with this release is to meet the community's growing need for new, modern, varied and cutting-edge approaches to understanding a journal's performance and influence around the world.

The January 2009 mid-year release of Journal Citation Reports, available to subscribers of JCR Web, delivers expanded analytic capabilities and includes the following new functionality:

NEW FUNCTIONALITY IN JCR WEB:

• Five-Year Impact Factor: Gives a broader range of citation activity for a more informative snapshot over time. For journals in subjects where citation activity continues to rise through several years, this allows more of their total citation activity to be included in a critical performance metric
• Eigenfactor^TM Metrics: Comprised of the Eigenfactor^TM Score and Article Influence^TM Score these popular new metrics are designed to reflect the prestige and citation influence of journals by considering scholarly literature as a network of journal-to-journal relationships
• Impact Factor “Box Plots”: A graphic interpretation of how a journal ranks in different categories
• Rank-in-Category Tables for Journals Covering Multiple Disciplines: Allows a journal to be seen in the context of multiple categories at a glance rather than only a single one
• Journal “Self Citations”:  An analysis of journal self citations and their contribution to the Journal Impact Factor calculation
