Kira Hopkins (OA Librarian at London School of Economics, and ex Copim project) has created a list of Diamond open access options which is freely available on Zenodo: Where can I publish a book open access without (necessarily) paying a fee?
Caveats and restriction
The list (which is shared with Kira’s permission) aims to act as a starting point for authors looking into their options for publishing open access books without a fee. While Kira’s definition of Diamond OA differs from the EDCH definition (there is an explanation on the Zenodo record), the list is a useful resource that can be built upon.
The list has been collated using Kira’s knowledge and experiences on the Copim Project (working on the Opening the Future OA funding model), and relies on details from public-facing publisher and funding scheme websites. It is primarily UK / US centric but has been supplemented by the addition of a small number of European Diamond OA publishers from the Diamond Open Access Book Publishers List published in September 2025 by Lena Ryzhová and Benedetta Siviero of the Diamond OA Expertise Center.
