Two-thirds of Wiley-Blackwell's Journal Portfolio now has an Impact Factor

Hoboken, N.J.

Wiley-Blackwell, the scientific, technical, medical, and scholarly business of John Wiley & Sons, Inc., today announced that two thirds of its journals (67% and 1,013 titles) have an Impact Factor according to the Thomson ISI® 2009 Journal Citation Reports (JCR).  This is a higher proportion of the list than any other major journals publisher.  Of these ranked titles, nearly a quarter are in the top ten of their subject category (332 titles) whilst two thirds are in the top half of their category.

Wiley-Blackwell has 36 number 1 rankings (from 33 titles, with Econometrica top of three, and Worldviews on Evidence-Based Nursing top of two categories respectively), the joint highest number of top ranked titles as a proportion of the list.  The Wiley-Blackwell journal CA-A Cancer Journal for Clinicians remains in first place overall with an Impact Factor of 87.925.

51 new titles were added to Wiley-Blackwell's listing in the JCR for 2009 with 4 titles re-listed.

Wiley-Blackwell's average Impact Factor saw a 5.3% rise last year.  This year, the company's average was 2.1, compared to 2.0 last year.  This is in the context of an overall 1.7% reduction in average Impact Factor between JCR 2008 and 2009.

Overall, Wiley-Blackwell published 11.2% of the journals, 11.3 % of the articles, and received 11.1% of the citations.

"We are delighted with the Impact Factor results this year", said Steve Miron, Senior Vice President, Wiley-Blackwell. "They reflect the hard work of our external Editors, society partners and Wiley colleagues to continually drive the quality of the journals that we publish and to ensure they meet the needs of authors and researchers alike".

Impact factors are a metric that reflect the frequency that peer-reviewed journals are cited by researchers, making them an important tool for evaluating a journal’s quality.

Within the 2009 Journal Citation Report were a number of key changes in the rankings for individual titles.
