This year, the ESAC initiative hosted a workshop on APC pricing mechanisms to discuss how institutions can develop their own goals in this respect, in order to progress towards a sustainable and transparent APC market. The workshop report outlines the participant’s common understanding of APC pricing as well as strategies to mitigate the potential risks associated with the APC-based publishing business model. The workshop results may help other institutions to better assess the APC market and to build on their goals when negotiating transformative agreements.
