This resource offers a curated list of Diamond Open Access book publishers that do not charge Book Processing Charges (BPCs) and are, in principle, open to authors regardless of institutional affiliation. It is intended to support researchers — particularly in the Netherlands, but also across Europe — in finding fair and accessible publishing options for academic books.
The list is manually verified and provided as a searchable Excel file. An “Additional information” column highlights any specific conditions set by individual publishers.
The list is updated quarterly. If you are aware of a Diamond OA book publisher that meets these criteria but is not yet included, or if you spot an error, please don’t hesitate to contact us.
