Impact factors for BMC journals

Matthew Cockerill, Official 2007 Impact Factors show excellent performance by BioMed Central journals, BioMed Central Blog, June 19, 2008.

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 40 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 17 greater than 3.0.
