Publishing open access DOES NOT equate to being in compliance with U.S. funding agencies' public access compliance policies. Policies will vary by agency but many require researchers to deposit their accepted manuscripts in the agency's chosen repository. Publishing as Gold OA is not a requirement for Public Access compliance. Public access policies are the result of two White House Office of Science & Technology Policy Memos: the 2013 Holdren Memo and the 2022 Nelson Memo.
On this page you will find links to the various policies as they are developed as well as any associated repositories.
