PHILADELPHIA and LONDON, June 17 /PRNewswire/ -- Thomson Reuters today announced the release of the 2009 Journal Citation Reports® (JCR). The most widely used tool for assessing the world's leading journals, JCR and the metrics it offers -- including Journal Impact Factor -- empower users to objectively evaluate a journal's performance and its influence on research globally.

Featuring more than 9,100 of the world's most highly cited peer-reviewed publications, the 2009 JCR includes 861 journals added through the Thomson Reuters Regional Content Expansion. This multi-year initiative aims to enrich the collection of regionally important and influential International journals represented in JCR and other Thomson Reuters services.

"For JCR subscribers across the world, JCR's annual release facilitates new discoveries," said Jim Testa, Vice President, Editorial Development & Publisher Relations at Thomson Reuters. "This is more apparent than ever considering the widely diverse group of journals added to the 2009 release as part of the Thomson Reuters Regional Content Expansion. This new, important content keeps JCR the truest barometer of journal influence in global research."

Included in 2009's release are features that help users visualize and evaluate the journal data in context, including:

Five-Year Impact Factor, which helps users evaluate journals in the context of their specific field. In the 2009 JCR release, 1,055 journals receive their first calculated Journal Impact Factors.
Eigenfactor™ Metrics that assess a journal's prestige and citation influence by considering scholarly literature as a network of journal-to-journal relationships.
Rank-in-Category Tables, a unique visualization tool illustrating at a glance a journal's performance in the context of multiple categories.
Journal "Self-Citations," an analysis of a journal's self citations and their effect on the Journal Impact Factor calculation.

Used by librarians, publishers, authors, researchers and bibliometricians alike, JCR offers a systematic, objective means to critically evaluate the world's leading journals with quantifiable, statistical information based on citation data. The 2009 release analyzes the performance of the world's most highly cited, peer-reviewed journals from 2,200 publishers in 78 countries.
