New and improved impact factors for BioMed Central journals in the 2008 JCR

15

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:

 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.

Blog updated 25th June 2009: Information on missing Impact Factors 

Blog updated 3rd July 2009: 59 Impact Factors, not 58 – thanks Gavin!  

Blog updated 6th July 2009: Corrected Impact Factor provided by Thomson Reuters for Journal of NeuroEngineering and Rehabilitation

Blog updated 1st October 2009: Thomson have released the updated online version of the JCR, including official Impact Factors for BMC Systems
Biology, Chemistry Central Journal,
Diagnostic Pathology, Journal of Cardiothoracic Surgery, Neural Development and Radiation Oncology (which had been omitted in error from the initial release) and providing corrected (increased) Impact Factors for Journal
of NeuroEngineering and Rehabilitation
and BMC Structural Biology (which had been understated in the initial release).

I, too, would like to know the impact factor of the Journal of Ethnobiology and Ethnomedicine.

It is said that the impact factors of new BMC journals will be shown in the update of JCR this year. But when will Thomsom Rheuters update their online version of JCR 2008 ?

Response to comments:

The Journal of Ethnobiology and Ethnomedicine is not yet tracked by Thomson Reuters as part of Web of Science, and so does not yet have an Impact Factor listed in the JCR. However, the citation data in Web of Science from other journals allows an unofficial Impact Factor to be calculated which provides a good estimate of what the Impact Factor would be. The 2007 unofficial Impact Factor for Journal of Ethnobiology and Ethnomedicine was 1.23.

BMC Psychiatry is tracked by Thomson Reuters and should receive its first official Impact Factor in June 2010. Its 2007 unofficial Impact Factor was 1.28.

BMC Pregnancy and Childbirth’s 2007 unofficial Impact Factor was 1.16.

[Updated unofficial Impact Factors based on 2008 citation data will be made available shortly.]

Because Molecular Brain only published its first articles in 2008, it is to early for any estimate of its Impact Factor to be made, official or unofficial.

Thomson Reuters have indicated that the corrected version of the JCR is likely to be released in the late Summer / early Fall.

Your previous answer is “The 2009 Impact Factors are expected to be released by Thomson Reuters in June 2010”.
We are now on 15th however, no impact factors appear online yet?
Thanks

Thomson Reuters tell us that the release of the 2009 Impact Factors is expected later this week.

Dr Sattaral,
Journal Impact Factors are published by Thomson Reuters in a database called Journal Citation Reports (JCR)
More info here:
http://en.wikipedia.org/wiki/Journal_Citation_Reports

Access to the JCR itself requires a subscription, but most publishers, including BioMed Central, share details of their journal’s Impact Factors upon release.
