Elsevier Announces 2010 Journal Impact Factor Highlights

AMSTERDAM, July 14, 2011 -

Elsevier, a world-leading provider of scientific, technical and
medical information products and services, today announced the
highlights of its journal Impact Factor performance in 2010.
According to the 2010 Journal Citation Reports^®
published by Thomson Reuters, Elsevier saw over 55% of its journal
Impact Factors increase from 2009 to 2010, while slightly over 49%
of non-Elsevier journals showed an increased Impact Factor. In
addition, 23% of Elsevier journals were ranked in the top 10% of
their category.

Glen Campbell, Executive Vice President, Global Medical Research
Journals said, “It continues to give us pride to be able to
announce increased Impact Factors year after year. It’s a tribute
to the authors, reviewers and editors we work with, as it’s their
dedication, professionalism and integrity that enable us to publish
world class-content. We are mindful however, that the Impact Factor
is just one of a number of quality indicators for journals.”

Martin Tanke, Managing Director of Elsevier’s Science &
Technology Journals, added, “We continue to look at ways to improve
the quality of our journals beyond the Impact Factor. Speeding up
the reviewing process, investing in tools that further streamline
the publishing process and continuous efforts to enhance peer
review are some of our top priorities in this area. Let there be no
doubt, however, that we are delighted to see this year’s
significant Impact Factor increases.”

The Lancet and all three Lancet specialty journals
improved their Impact Factors this year. The Lancet went up
from 30.758 to 33.633, ranking 2^nd in the Medicine,
General & Internal category. Lancet Infectious Diseases
and Lancet Neurology retained their #1 rankings in their
respective categories, while Lancet Oncology saw its Impact Factor
increase from 14.470 to 17.764.

Cell, the flagship journal of Cell Press, saw its Impact
Factor increase from 31.152 to 32.401 and remains the number one
research journal in the Cell Biology and Biochemistry &
Molecular Biology subject categories. The impact factor for
Immunity showed an impressive 18% increase to 24.221. Among
Cell Press’s more recent suite of journal launches, Cancer
Cell delivered a strong performance by showing an increase of
almost 7% to 26.925, while Cell Stem Cell (increase to
25.943)and Cell Host & Microbe (increase to
13.728)continue to grow in their third year of impact factors.

In addition, 67 Elsevier journals earned their first Impact
Factor this year. Some of these journals received very impressive
scores including:

• Communications in Non-Linear Science and Numerical
  Simulation (2.697) - entering in the top ten of three
  categories:
  • 6^th in the Mathematics, Applied category of 236
    journals,
  • 5^th in the Mathematics, Interdisciplinary
    Applications category of 92 journals,
  • 5^th in the Physics, Fluids & Plasmas category of
    31 journals.
• History of the Family (0.595) - entering the Orthopedics
  category ranked 8^th of 26 journals.
• JACC-Cardiovascular Imaging (5.528) - entering the
  Radiology, Nuclear Medicine & Medical Imaging category ranked
  4^th of 111 journals and ranked 11^th in the
  Cardiac & Cardiovascular Systems category of 114 journals.
• JACC-Cardiovascular Interventions (5.862) - entering the
  Cardiac & Cardiovascular Systems category of 114 journals in
  10^th place.

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.
