The 2022 OSTP ‘Nelson Memo’ sets out policy recommendations for federal research funding bodies to update or establish mandatory public access policies. Despite recent legal wrangling, it seems likely that a significant number of researchers in the US – and any teams they collaborate with internationally – will be required comply with zero-embargo green open access requirements for future research projects. This webinar will explore some anticipated impacts from these policies, set out how publishers are responding, and discuss some of the challenges still to be addressed in order to make public access to research outputs a reality.
