This community collection gathers papers, reports, videos, and other outputs related to open access (OA) books created by or involving staff of the OAPEN Foundation.

The OAPEN Foundation (OAPEN) is an independent, not-for-profit Dutch foundation registered at the National Library in The Hague. Dedicated to supporting open access (OA), peer‑reviewed scholarly books, we manage three key infrastructures:

• The OAPEN Library: A global digital library for hosting and disseminating scholarly OA books, free to use, no registration required.
• Directory of Open Access Books (DOAB): A free global discovery service developed in partnership with OpenEdition to index peer-reviewed OA books
• OAPEN Open Access (OA) Books Toolkit: A free resource intended to help authors to better understand open access book publishing and to increase trust in open access books.

OAPEN is also an active voice in the wider open access books community.
