*"BioMed Central calculates unofficial impact factors for journals that have
published a significant number of research articles but do not yet have an
official impact factor. These unofficial impact factors use the same
citation data and methodology used by Thomson Scientific's official impact
factor calculations.*

* *

*Newly calculated unofficial 2006 impact factors show a significantly
increased citation rate for BioMed Central journals. For example, BMC
Biology <http://www.biomedcentral.com/bmcbiol/>* and *BMC
Medicine<http://www.biomedcentral.com/bmcmed/>
*, the flagship journals of the BMC series, both increased their unofficial
impact factors significantly. The 2006 unofficial impact factor for *BMC
Biology <http://www.biomedcentral.com/bmcbiol/>* is 4.43 (up from 3.81 in
2005) while for *BMC Medicine <http://www.biomedcentral.com/bmcmed/>* the
2006 figure is 4.17 (up from 2.52 in 2005).
