Wiley Announces Significant Increases in its Journal Impact Factors

Global publisher John Wiley & Sons, Inc., announces significant 
increases in Impact Factors for its journals across the majority 
of subject areas, according to the Thomson ISI 2005 Journal 
Citation Reports.

Impact Factors reflect the frequency that peer-reviewed journals 
are cited by researchers, making them a vital tool for evaluating 
a journal's influence.

Globally, 65% of Wiley journals included in the Journal Citation 
Report's Science Edition increased their Impact Factors. 
Furthermore, 58% of the Wiley journals included in the Social 
Science Edition increased their Impact Factors, with a 12.7% 
increase in 2005 versus 2004.

Highlights in the medical sciences include the Journal of 
Pathology (published on behalf of the Pathological Society) which 
now ranks number one in the category of Pathology with an Impact 
Factor of 6.213, and Arthritis & Rheumatism (published on behalf 
of the American College of Rheumatology) which increased its 
Impact Factor and remains number one in Rheumatology. Reviews in 
Medical Virology now ranks second in Virology.

Angewandte Chemie International Edition, a journal of the German 
Chemical Society, increased its Impact Factor once again. Now at 
9.596, the journal is positioned significantly higher than 
comparable publications.

In the area of physical sciences, Mass Spectrometry Reviews ranks 
number one in the Spectroscopy category for the seventh 
consecutive year; Medicinal Research Reviews leads the Medicinal 
Chemistry category for the third straight year; and Advanced 
Synthesis & Catalysis retains its number one position in the 
Applied Chemistry category.

In all, 46 Wiley journals were ranked in the top ten of their 
respective subject areas. In addition to those noted above, these 
journals include Ultrasound in Obstetrics and Gynaecology, 
(published on behalf of ISUOG), Annals of Neurology, Hepatology, 
Liver Transplantation, Rapid Communications in Mass Spectrometry, 
Proteomics, ChemBioChem, Advanced Materials, Journal of Polymer 
Science Part A: Polymer Chemistry, Journal of Experimental 
Zoology Part B: Molecular and Developmental Evolution, 
Evolutionary Anthropology, The Anatomical Record Part A, 
Behavioral Sciences and the Law, Journal of Organizational 
Behavior, Strategic Management Journal, and Human Resource 

Several journals gained their first Impact Factor including: 
Dyslexia, Wind Energy and Pharmaceutical Statistics (published on 
behalf of PSI). The journal Small, the first interdisciplinary 
journal of nano and micro science and technology, is also showing 
tremendous strength after only one year of publication. Launched 
in 2005, Small is already listed in five categories and has 
received an Immediacy Index of 1.255, ranking it number two in 
the Nanoscience and Nanotechnology category.

The International Journal of Methods in Psychiatric Research - 
new to Wiley with the acquisition of Whurr Publishers Ltd. in 
2005 - witnessed a significant increase in its Impact Factor to 
3.550 and is now ranked in the top ten of Psychiatry journals.
