Amsterdam, 7 July, 2010 – Elsevier, the leading publisher of scientific, technical and medical information products and services, today announced the highlights of its journal Impact Factor performance in 2009. Elsevier saw over 65% of its journal Impact Factors (IFs) increase from 2008 to 2009. According to the 2009 Journal Citation Reports® published by Thomson Reuters, Elsevier journals took the #1 position in 57 of 230 categories (up from 51 of 229 last year) across all of the sciences and social sciences.

This year there were 95 Elsevier journals that increased their IF by more than 50% over their 2008 scores. Amongst the biggest movers are journals in energy & fuels, climate change, sustainable development and banking & finance, demonstrating Elsevier’s leadership at the cutting edge of research into today’s global challenges.

Glen Campbell, Executive Vice President and head of Elsevier’s health sciences journals said of the results, “These significant Impact Factor increases, as well as those in more than 61% of our medical journals, reflect the dedication of our editors, reviewers, and authors, the high quality of our editorial content and our sharpened focus on author services.”
