Wiley-Blackwell, the STM and scholarly publishing business of John Wiley & Sons, Inc., US, has announced that it has more than 900 journals included in the 2007 Journal Citation Report. Of these, many showed dramatic increases in Impact Factors across the majority of subject areas. Impact factors are a metric that reflect the frequency that peer-reviewed journals are cited by researchers, making them one tool for evaluating a journal's quality.
Wiley-Blackwell titles were ranked number one in 31 categories including Mass Spectrometry Reviews (Spectroscopy), Addiction (Substance Abuse), Arthritis & Rheumatism (Arthritis Care & Research), Child Development (Psychology, Education), and Global Ecology and Biogeography (Geography, Physical). Highlights in the medical sciences include Obesity Reviews (Endocrinology & Metabolism) with its first Impact Factor of 7.821 and Cochrane Database of Systematic Reviews (Medicine, General & Internal) with 4.654. The Journal of Sexual Medicine continued to increase its place in the field at 6.199, and ranking second in the urology and nephrology category.
In the field of chemistry, Advanced Synthesis and Catalysis confirmed its number one position in the applied chemistry category for the fourth straight year; Fuel Cells received its first Impact Factor of 3.273; and for the last two years, Angewandte Chemie, a journal of the German Chemical Society, has received an Impact Factor above 10.
In addition, Clinical Implant Dentistry and Related Research received its first Impact Factor; the International Endodontic Journal added almost a point increase to its Impact Factor; and Periodontology 2000 increased its ranking from fourth to number one in its field. Wiley-Blackwell now has the top six dentistry journals in the top 10 in the dentistry, oral surgery and medicine category.
In the social sciences and humanities, a number of journals increased their Impact Factors substantially including the British Journal of Sociology with an increase of 145 percent and Sustainable Development which increased its Impact Factor by 173 percent.
In the area of life sciences, Biological Reviews increased its Impact Factor from 5.565 to 8.833; FEMS Microbiology Reviews increased its Impact Factor to 9.25; and for the fourth consecutive year Ecology Letters increased its Impact Factor-now 8.204.
