1,192 Wiley Journals Have an Impact Factor;

John Wiley & Sons, Inc., today announced a continued increase in the proportion of its journal titles indexed in the Thomson Reuters® 2012 Journal Citation Reports (JCR), with 1,192 (approximately 77%) titles now indexed, up from 1,156 in the 2011 JCR. Wiley titles now account for the largest share of journals in 50 categories.
In the 2012 JCR the number of Wiley journals with a top category rank increased by 19% (4) and the number of Wiley titles indexed in the top ten of their categories also increased by 11% (27). Of publishers with more than 100 journals indexed in the 2012 JCR, Wiley saw the largest proportion of titles (close to 60%) increasing in Impact Factor (IF).
- 1,192 Wiley journals now have an IF.
- 25 Wiley journals achieved a top category rank across 31 JCR categories, up from 21 in 2011.
- 264 Wiley journals achieved a top 10 category rank across 341 categories, up from 237 in 2011.
- 59.4% of Wiley journals increased their IF.
- Wiley titles appear in 218 of the 232 subject categories.
- Wiley journals make up the largest share of journals in 50 categories.
- CA – A Cancer Journal for Clinicians, a Wiley published journal, continues to have the highest IF in the JCR.
“We are honoured to work with the editors, societies, and publishing teams behind such high quality publications, and it gives us great pleasure to see the portfolio go from strength to strength. All those involved, our colleagues and our partners, should be delighted by the latest JCR results,” said Steven Miron, Senior Vice President in Wiley’s Global Research business.
One of the largest changes this year is the partnership between Wiley and the American Geophysical Union, whose portfolio of influential geoscience and geophysics titles is responsible for 6% of citations to journals published by Wiley in the 2012 JCR. Of these titles, Journal of Advances in Modeling Earth Systems entered the Meteorology & Atmospheric Sciences category in the top ten, with an IF of 4.117.
Other success stories include the first appearance of Advanced Energy Materials, entering the JCR with an Impact Factor of 10.043 – putting it in the top ten of all five of its JCR subject categories. Advanced Energy Materials joins the successful Advanced Materials series, which includes titles such as Advanced Functional Materials (9.765) and Advanced Materials (14.829). Collectively, these journals appear in the top ten of a JCR subject category 15 times, asserting the traction of this journal series within the scientific community.
This year also sees a continuing increase in IF of CA – A Cancer Journal for Clinicians, published on behalf of The American Cancer Society. Last year this journal became the first to achieve an IF over 100 and has this year broken its own record with an IF of 153.459 at 0% self-citation, a 51% increase from its 2011 IF. The Impact Factors of its two sister titles, Cancer (5.201) and Cancer Cytopathology (4.434), also increased.
The WIRES (Wiley Interdisciplinary Reviews) portfolio has continued to increase in strength, with seven WIRES titles now indexed in the JCR, three of which received their first IF this year.
Impact factors are a metric that reflect the frequency that peer-reviewed journals are cited by researchers, and are often used as a tool for evaluating a journal’s quality.
Highlights in Chemistry, Physical Sciences and Engineering:
Four publications rank at number one in their category this year, including Computer-Aided Civil and Infrastructure Engineering (4.460 and number one in three categories); Acta Crystallographica Section D which is distributed on behalf of the IUCR and further increased its IF to 14.103, now ranking number one in two categories; the International Journal of Energy Research (1.987); and WIREs Computational Molecular Science (5.738) which received its first IF and entered the JCR at number one of the Mathematical & Computational Biology category.
Other journals with impressive first IFs include Advanced Energy Materials (10.043); Greenhouse Gases: Science and Technology (2.679/ jointly published with the SCI); the International Journal of Applied Glass Science (1.548/published on behalf of the American Ceramic Society); and WIRES Data Mining & Knowledge Discovery (1.422). These excellent results underline Wiley’s constant efforts for innovation in publishing.
Angewandte Chemie, a journal of the German Chemical Society published under the Wiley-VCH imprint, saw its IF rise further to 13.734. It has strengthened its position as the leading multidisciplinary chemistry journal publishing both primary research and review articles.
