Official 2007 Impact Factors show excellent performance by BioMed Central journals


The 2007 Journal Citation Report from Thomson Reuters, which has just been released, confirms the excellent performance and growing reputation of BioMed Central’s journals.

There are now 42 BioMed Central journals which have official Impact Factors. Highlights of this year’s Impact Factors include an impressive showing by BMC Biology, the biological flagship journal of the BMC series, which debuted with an Impact Factor above 5.0, and Molecular Pain, which confirmed its status as one of the leading journals in Anesthesiology and Pain Medicine with an impressive Impact Factor of 4.13.

Malaria Journal retained its status as the No 1. ranked journal in the field of Tropical Medicine, while Retrovirology appeared for the first time in the JCR, ranking 5th of 25 journals in the Virology category, ahead of  long established titles such as the journal Virology. BMC Plant Biology jumped straight into the upper echelons of the Plant Science rankings, with an Impact Factor of 3.23, which places it 18th of 152 journals in that area.

Overall, the median Impact Factor of a BioMed Central journal has increased from 2.77 to 2.91. Last year, BioMed Central had 4 journals with Impact Factors above 4.0 and 10 journals with Impact Factors above 3.0. This year, we have 8 journals above 4.0, and  19 greater than 3.0.

 * In the case of Microbial Cell Factories, the Impact Factor released in the 2007 JCR appears to be in error, under-reporting citations as a result of a technical issue. Thomson Reuters have confirmed this issue and have indicated that they will release a corrected official Impact Factor shortly. In the meantime, a predicted 2007 Impact Factor is shown, based on Web of Science citation counts.

In addition to the 40 journals listed above, many more BioMed Central journals are already tracked by Thomson Reuters and are due to receive official Impact Factors in the next year or two. For information on the expected timing of future Impact Factors, as well as unofficial Impact Factors for journals not yet tracked by Thomson Reuters, see BioMed Central’s Impact Factor FAQ page.  Another valuable resource is SCImago, a recently launched free set of journal citation metrics based on citation data from Scopus, which offers a more comprehensive picture of citation metrics for journals than that provided by the Journal Citation Report.

Update 2nd July 2008: Thomson Reuters have just released two additional official 2007 Impact Factors, for Biology Direct (3.29) and Algorithms for Molecular Biology (1.63). These new Impact Factors will be included in the maintenance release of the JCR later this year.

Update 29th July 2008: Thomson Reuters have confirmed the correct Impact Factor for Microbial Cell Factories, which had an erroneously low Impact Factor in the initial release of the JCR. The correct Impact Factor is 3.36.

Dear colleagues,

I would like to congratulate the BMC journals for the impressive performance.

Keep up with the good work!

BMC journals are doing remarkable contribution for open access of high impact sholarly literature. Now developing world researchers are also participating in publication work.

More journals may be added to thir list,
