We have just received confirmation from Thomson Reuters of official 2007 Impact Factors for Biology Direct (3.29) and Algorithms for Molecular Biology (1.63).

Impact Factors for these two journals, both of which focus on aspects of computational biology, had been expected in June 2008, when the 2007 edition of the Journal Citation Report was released . However, as occasionally happens, technical issues delayed the calculation of Impact Factors for these particular journals. We are glad to note that these issues were promptly addressed by Thomson Reuters, and these new official Impact Factors should soon be available through the online edition of the  Journal Citation Report.
