From a BioMed Central Announcement:
The Netherlands Organisation for Scientific Research (NWO) today announced the membership agreement with BioMed Central and SpringerOpen. Publication costs for research articles published by researchers funded by NWO for articles published no later than 2008, who chose to publish via BioMed Central will now automatically be covered (up to the maximum as defined by the NWO Incentive Fund Open Access Publications)
Under the terms of the arrangement, NWO, will centrally cover all of the article processing charge (APC) for Dutch researchers who wish to publish via BioMed Central in any BioMed Central, Chemistry Central or SpringerOpen peer-reviewed open access journal.
This is in line with NWO’s ‘Open Access Incentive Fund’, designed to encourage its researchers to publish open access articles and books as well as conference sessions and journals.
