The latest edition of Thomson Reuter’s Journal Citation Reports has just been released, with official Impact Factors for a total of 59 BioMed Central journals†. Impact factors are by no means a perfect quality metric, but these journal citation data provide strong evidence of the growing success of BioMed Central’s open access journal portfolio.
Highlights include:
- Impressive initial Impact Factors for two key titles in the BMC series: BMC
Medicine and BMC Systems
Biology - Initial Impact Factor for Nutrition
& Metabolism, placing it in the top 25% of the NUTRITION & DIETETICS category - Initial Impact Factor of 3.45 for Neural Development
- An increased Impact Factor for BMC
Bioinformatics, now ranked #3 of 28 in MATHEMATICAL & COMPUTATIONAL BIOLOGY. - An increased Impact Factor for BMC
Plant Biology, which is now ranked #14 of 152 in PLANT SCIENCES (one of the top 10 research journals listed in the category) - An increased Impact Factor of Malaria
Journal . The TROPICAL MEDICINE category now has open access journals in both the #1 and #2 spots. - Excellent performance by BioMed Central’s cancer journals: Breast
Cancer Research and Molecular
Cancer‘s Impact Factors both increased to above 5.0, while BMC
Cancer’s Impact Factor is now above 3.0. - Improved Impact Factors for society-affiliated journals published by BioMed Central: Geochemical
Transactions , Journal of
Cardiovascular Magnetic Resonance and Acta Veterinaria Scandinavica - A significantly increased Impact Factor for Critical Care, ranked #4 of 21 in CRITICAL CARE MEDICINE.

† The Impact Factor for these titles are not yet present in the online version of the JCR database due to a technical problem at Thomson Reuters. The Impact Factor’s shown are official Impact Factors provide by Thomson Reuters and will appear in the update to the 2008 JCR later this year.
The following titles: Substance Abuse Treatment, Prevention, and Policy, Molecular Neurodegeneration and Implementation Science, although tracked in Web of Science since 2006 and so expected to have Impact Factors this year, did not have data extracted by Thomson Reuters in time to generate a 2008 Impact Factor, so will appear in the 2009 JCR.
* Thomson Reuters have confirmed that the Impact Factor for Journal of NeuroEngineering and Rehabilitation originally listed in the 2008 JCR (1.127) was erroneously low. They have calculated a corrected value of 2.085, which is included in the updated online version of the 2008 JCR released in late September 2009.
