This correction to an earlier post bears repeating! According to Wim van der Stelt, Springer, EVP Business Development, Springer, owner of BioMedCentral, did NOT sign the anti-FRPAA letter of the AAP/PSP; Springer is currently not even a member! In fact, as reported in full here, Springer, owner of BMC, has quite an enlightened approach to open access.
It is my delight to profusely apologize to Springer (owner of BMC) for the mix-up.
