This pilot is our way of asking our customers to become actively involved in the funding of Open Access books. Libraries are paying to get the book early, and to fund a wider program that will benefit them, their customers and the wider Academy directly. There are a few important things that our program is not. It is not a program in response to any particular government, funder or society mandate. Rather, it is the implementation of the core OA principles of availability, inclusivity and dissemination because we believe in them. It is also not a mechanism for funding all our publishing. We are asking our customers and partners to buy what they would want to buy anyway, in the knowledge that by doing so they will have the additional bonus of helping those books to reach a wider audience.
