The science published in Cell Press journals continues to deliver high impact across the research community as reflected in the measures of citation released this week in the 2012 Journal Citation Reports© (JCR) published by Thomson Reuters. Looking across impact factor (IF) and immediacy index as measures of a journal's short-term value as well as 5-year IF and cited half-life as indications of a journal's robustness and longevity, Cell Press journals made significant increases in multiple citation-based measures of impact.
Cell continues to lead in its field with an impact factor of 31.957, and remains the number one research journal in the Cell Biology and Biochemistry & Molecular Biology categories. Currently celebrating 25 years of exciting neuroscience, Neuron has delivered strong growth in impact over the last 3 years, rising from 13.260 in 2009 to 15.766 in 2012. Now in its 50th volume, Molecular Cell's impact factor grew by 8% from 14.178 to 15.280. In just its 6th year of publication, Cell Stem Cell is holding steady with an impact factor of 25.315, having risen rapidly from 16.826 in 2008.
Seven of the fourteen Trends review journals published by Cell Press increased in impact. In particular Trends in Cognitive Sciences grew by 27% from 12.586 to 16.008, Trends in Biochemical Sciences went up from 10.847 to 13.076, an increase of over 20%, and Trends in Endocrinology & Metabolism grew by 10% to 8.901.
Launched in 2007, Cell Host & Microbe increased its immediacy index by 29% up from 2.274 in 2011 to 2.943, and Cell Metabolism's immediacy index increased by 24% from 2.624 to 3.250. Trends in Microbiology's immediacy index went up by 58% from 1.365 to 2.153, and other notable increases include Trends in Cognitive Sciences (64%), Trends in Immunology (24%), and Trends in Pharmacological Sciences (24%).
For many of these journals the trends of increase in the 2-year IF and immediacy index are also reflected in the 5-year IF and cited half-life. These measures reflect that our published articles are cited more frequently in both the shorter- and the longer-term, illustrating the timeliness and longevity of their value and impact.

In 2012 the Cell Press primary research and Trends review journals received over 715,000 citations, representing 6% growth on 2011. As well as considering traditional citation-based measures, several months ago Cell Press added article-level altmetrics to its website so that readers can track the real-time community response to individual papers.
"We're are delighted to see that our editorial efforts in engaging with the scientific community, identifying exciting science, providing a fast, fair, informed peer review, and having a clear editorial vision have paid off in continuing to provide content of high value and impact to the scientific community." said Emilie Marcus - CEO, Cell Press, and Editor-in-Chief, Cell.
Cell Press owes thanks to all the authors who entrusted us with their best research articles and reviews and to the reviewers who helped us understand the strengths and limitations of each paper. Thanks also to all our readers who were inspired by the papers we published in their own research and went on to build on them and cite them.
