Thomson
Reuters have informed us that another three BioMed Central journals have been
accepted and are well on their way to receiving their first Impact Factors next
year in June 2011.

BMC Ophthalmology, Cell Division and Epigenetics & Chromatin have recently been accepted for citation
tracking by Thomson Reuters, which takes the total of tracked BioMed Central
journals to 102.

For journals
that have not been tracked for long enough to have an Impact Factor, or are not
yet tracked by Thomson Reuters, it is possible to calculate an unofficial Impact Factor, which we have done for these and a number of other journals. Unofficial 2009 Impact Factors were calculated using the same established methodology as is used for calculating the Impact Factor. 

These journals have developed strong reputations in their fields and this
news is a good indicator of their success to date. We extend our congratulations
to the Editors-in-Chief of all of these titles.

Full
details on indexing of all BioMed Central titles is available from our website.
