Other Elsevier journals continue their long-running trend of increased IFs, in particular Biomaterials (http://www.elsevier.com/locate/biomaterials) (increasing yearly since 2003) and The Journal of Allergy and Clinical Immunology (http://www.elsevier.com/locate/jaci) which has shown consistent growth over the past five years.
Glen Campbell, Senior Vice President of U.S. Health Sciences Journals said, "Each annual announcement of impact factors confirms the depth and excellence of our health sciences journal publishing program. The superior performance of so many of our journals this year is a sign of the strong partnerships we have with our journal editors and our societies. This year's impact factor growth is one indication of the hard work and focus on quality of these collaborations."
"The fact that Elsevier's overall results are amongst the best in the industry is a true indication of the impact of the increased focus on quality we have placed on our journals in the past three years. The increased impact factors, across the board, are evidence that the research we publish is of the highest quality," remarked Martin Tanke, Managing Director of Science and Technology Journals. "We are grateful for our strong network of editors we partner with, who work with us each day to build our journals to some of the best in their fields."
The impact factor is a measure of the frequency with which the average article in a journal has been cited in a particular year. The impact factor helps to evaluate a journal's relative importance, especially when compared with others in the same field.
