Thomson Reuters Releases 2008 Journal Citation Reports

New Titles and Metrics Include Five Year Impact Factor and Eigenfactor(TM)
Metrics

PHILADELPHIA and LONDON, June 22 /PRNewswire/ -- The Healthcare & Science
business of Thomson Reuters today announced the release of the 2008 Journal
Citation Reports, available to subscribers of the JCR. These metrics have come
to define journal performance across disciplines and institutions worldwide.
The 2008 JCR contains more than 400 new titles, including more than 350 titles
that will have their first published Journal Impact Factor.

The release of the 2008 Journal Citation Reports includes the first-ever
update to the newly introduced Five Year Impact Factor and Eigenfactor(TM)
Metrics in JCR Web. Eigenfactor(TM) Metrics use citing journal data from the
entire JCR file to reflect the prestige and citation influence of journals by
considering scholarly literature as a network of journal-to-journal
relationships.

"The research community anticipates the annual release of JCR as it always
means new discovery," said James Testa, Senior Director, Editorial Development
and Publisher Relations at Thomson Reuters. "The addition of new metrics such
as the Five Year Impact Factor is a reflection of our commitment to providing
publishers and scholars with tools that allow a more multifaceted
understanding of a journal's place in the world."

JCR presents quantitative data that provide an objective way to evaluate the
world's leading journals and their impact and influence in the global research
community. In addition to the benefits these metrics offer to authors and
institutions, JCR and Impact Factors may be used by publishers to benchmark
journal performance against competitors to create a better focused market
strategy.

JCR covers more than 8,000 of the world's most highly cited, peer-reviewed
journals from 66 nations. The production of the 2008 JCR included the analysis
of more than 44 million cited references from journals, and proceedings. For
