As is the case with open access journals for some time, there is no institutional or funders policy to financially support open access books
Some universities as Groningen, Leiden and Tilburg support open access books through participation in Knowledge Unlatched or by paying the costs of the Book Processing Costs (BPC) on behalf of the authors to publishers
Amsterdam University Press is primary partner in the OAPEN project, concerned with the Open Access publishing of humanities and social sciences monographs.
