Join - Publishers

OAPEN is dedicated to open access, peer-reviewed books. OAPEN operates two platforms, the OAPEN Library (, a central repository for hosting and disseminating OA books, and in partnership with OpenEdition, the Directory of Open Access Books (DOAB,, a discovery service for OA books.

We work with publishers to build a quality-controlled collection of open access books, and provide services for publishers, libraries and research funders in the areas of hosting, dissemination, quality assurance, deposit, and digital preservation.

Publishers can join OAPEN if they publish academic, peer reviewed books that are made freely available, or published under an open license. OAPEN will require a description of the peer review process, to check if it meets academic standards.
