The principles are based on the experiences of LIBER libraries in the past two years, and aim to guide libraries and consortia as they shift from a reader-pays model (subscription licensing) to an author-pays model based on Article Processing Charges (APC).
With these principles, research libraries are encouraged to make the move from paying for information access to organizing the publishing costs for their researchers.
[The] Five Principles are part of LIBER’s ongoing commitment to facilitate knowledge exchange between its libraries, national governments and stakeholders. They are inspired by other statements including the Amsterdam Call for Action on Open Science and the OA2020 Initiative.
