The OpenAPC initiative collects and disseminates datasets on fees paid for open access publishing on GitHub under an open database license.

We aggregate data on Open Acess journal articles (APCs), Open Access Books (BPCs) and data on articles published under transformative agreements (Like Springer Compact or Wiley DEAL). All data is provided voluntarily by universities and other HEI, funders or national consortia.

OpenAPC is located at Bielefeld University Library. The project was set up in collaboration with the DINI working group Electronic Publishing. Since 2021 it is part of OpenAIRE Nexus.
