Open Access funding usually means funding for APCs (gold OA – article publishing). Funding for Book Publication Charges/Costs (BPC) is not as common as funding for APCs but there are quite a few funding options for Open Access books.
To have a clear overview I thought it would be useful to share all available information of these funds. I stored a version in Figshare, which can be found following this DOI: https://doi.org/10.6084/m9.figshare.5208898.v1
The Funder’s List is also in a Google Sheet. If you have any additions or experiences with a specific fund, please feel free to contact me using the contact form or add information to the google sheets by using comments.
