Academic publisher SAGE has reported strong performance and continued growth across its journals portfolio in the Journal Citation Reports® (JCR) Thomson Reuters, 2015.
With over 500 journals now ranked in the JCR, SAGE continues to experience consistent growth within the reports, achieving a 31 percent increase over the past five years. In this year's reports, over 100 SAGE journals have received a top 10 category rank, with 23 journals receiving their first Impact Factor (IF). 220 titles are now placed in the top 30 percent of the JCR, and 52 percent of SAGE journals are ranked within the top half of their subject category. In the 2014 reports SAGE publishes the market leading journal within 13 categories.
Over the last five years, SAGE has seen a 51 percent increase in the number of titles in the SCI index, primarily due to strategic acquisitions and organic growth across the medical, engineering and technology disciplines, with SAGE now being marked out as one of the top five publishers of medical journals in the world. SAGE continues to significantly grow its coverage within the SCI with 181 journals now ranked and 47 journals in the top 25 percent of their SCI category.
Particular highlights include Statistical Methods in Medical Research (4.472), Journal of Dental Research (4.139), Neurorehabilitation and Neural Repair (3.976) and International Journal of Robotics Research (2.540), all being ranked #1 in their categories. Two SAGE neurology journals, Cephalagia and Multiple Sclerosis Journal also received high IFs of 4.891 and 4.822 respectively. Additionally, four of SAGE's 14 recently-launched Therapeutic Advances journals received their first IF in the 2014 reports; Therapeutic Advances in Gastroenterology (3.925), Neurological Disorders (3.140), Medical Oncology (2.827) and Respiratory Disease (1.949).
A total of 175 journals in BioMed Central's publishing portfolio now have impact factors in the recently published Journal Citation Report 2015, of which 104 journals rank in the top half of their categories.
Nine journals received their first impact factor. Biology of Sex Differences gained an impact factor of 4.84, placing it in the top quartile of both of its categories of Endocrinology&Metabolism and Genetics&Heredity.

BioMed Central's flagship journals have also seen increases in their impact factors over the last year. Genome Biology now has an impact factor of 10.81. This makes it seventh out of all 167 journals in the Genetics&Heredity category and the highest ranking open access journal in both of its categories. It is also the highest ranking open access journal in the Biotechnology and Applied Microbiology category according to its Eigenfactor - a measure which takes into account how often the journal is cited in a highly-cited journal.
BMC Biology's impact factor has grown to 7.98, making it fourth out of 85 journals in the Biology category. BMC Medicine is the second highest ranking open access journal in the Medicine, General&Internal category, with an impact factor of 7.25, and ranks 10 out of 153 journals in that category overall. The journal has also had articles with an Altmetric score of over 900 - a measure that takes into account an article's impact in terms of news coverage and social media.
Since transferring to BioMed Central in 2008, the Journal of Experimental&Clinical Cancer Research has seen its impact factor rise each year to a current high of 4.43. This places it in the top quartile of the Oncology category.
Genetics Selection Evolution is the highest ranking journal in the Agriculture, Dairy&Animal Science category, with an impact factor of 3.82. The society journal, owned by the French government agency for agriculture, has seen continuous growth in its impact factor since it transferred to BioMed Central in 2009.
The Journal Citation Reports 2015® (JCR), recently released by Thomson Reuters, lists a total of 1,595 Springer journals, with 37 Springer journals joining the list for the first time.
Significantly, in 2014, 82 percent of the Springer journals in the list were cited more frequently than in the previous year. Well over one half (57 percent) of Springer journals increased their impact factor in 2014 over the 2013 figure.
The open access journals in Springer's portfolio, which includes BioMed Central, fared particularly well. Thirteen open access journals received their first impact factor, bringing the total of Springer open access journals in the JCR to 202. This is over one third (36 percent) of Springer's 566 open access journals. Springer is a leader in open access publishing, helping to enhance the scope, availability and quality of peer-reviewed research conducted worldwide.
STM publisher Elsevier has announced the highlights of its journal Impact Factor performance in 2014. According to the 2014 Journal Citation Reports® (JCR) published by Thomson Reuters, Elsevier saw 55 percent of its journal Impact Factors increase from 2013 to 2014, ahead of the aggregate across other journals. In 2014, Elsevier journals occupied the top rank in 62 subject categories, up from 61 in 2013.
An additional 14 Elsevier journals have risen to the top of one or more of their subject categories, and 25 journals have received an Impact Factor for the first time.

Cell, the flagship journal of Cell Press, remains the top research journal in the "Biochemistry&Molecular Biology" and "Cell Biology" categories. Cell Press' open-access titles continue to draw attention, with Stem Cell Reports debuting this year with an Impact Factor of 5.365, while Cell Reports builds on last year's inaugural success with an increase of 16% to 8.358. The Trends review journal series continues to flourish, embodied by Trends in Cognitive Sciences which has more than doubled its Impact Factor in just 4 years from 9.686 to 21.965.
Of the 426 titles in the JCR that Elsevier publishes on behalf of societies, 266 (or 62%) saw their Impact Factors increase in 2014. And with an increase of 8% the Journal of the American College of Cardiology retains its top ranking in the "Cardiac&Cardiovascular Systems" category.
Impact Factor evaluates a journal's citation impact when compared to others in the same field. It provides a ratio of citations to the journal normalized by an estimate of the journal's scholarly article contribution. The 2014 Impact Factor takes into account citations in 2014 compared to papers published in 2012 and 2013.
Twenty-five IOS Press journals are currently included in the JCR, with 64 percent of titles showing an increase. Particularly noteworthy is Journal of Intelligent&Fuzzy Systems, a well-established journal that has achieved an impressive 94 percent Impact Factor increase. It ranks 45th out of 123 journals in the competitive Computer Science: Artificial Intelligence category with an Impact Factor of 1,812.
Other journals that have achieved strong Impact Factor growth include Fundamenta Informaticae (50%, with an IF of 0,717), Cancer Biomarkers (45%, with an IF of 1,721), Isokinetics and Exercise Science (38%, with an IF of 0,488) and WORK (89%, with an IF of 0,32).
IOS Press is pleased that a growing majority of its journals continue to show increased Impact Factors in Thomson Reuters Journal Citation Reports. JCR is the recognized authority for evaluating journals. The constant quality of metrics the Journal Citation Reports offers to researchers, authors, publishers, and institutions sets it apart.
