Knowledge Unlatched (KU) and OpenAPC, part of the INTACT project and located at Bielefeld University Library, are expanding the OpenAPC dataset to support the inclusion of Book Processing Charges (BPCs). The first deposit includes all of the payments made by KU to publishers for the KU Select programs, equaling almost 1,000 books. KU is also planning to share further transactional data for the other collections for which it collects funding.
This aligns with and is a natural extension of the KU mission to share impact reports and financial information openly with customers and the public. It marks the start of a new public database for OA books.
The current dataset, which will be expanded after the summer, can be found here:
