Grant proposal submitted by Invest in Open Infrastructure to the National Science Foundation (US) in May 2023. From the proposal summary: "This EAGER project will advance our knowledge of the costs involved in publishing US federally funded research outputs in a range of publicly accessible venues. Using a mixed research model, we will produce insights, tools, and intervention strategies to highlight and mitigate current disparities between institutions and researchers in different research tiers and institution types that may otherwise be exacerbated in the national effort to demonstrate compliance by 2025 with the OSTP Memo on Ensuring Free, Immediate and Equitable Access to Federally Funded Research (Nelson 2022)."
