Powell | Open But Hidden: Open Access Gaps in the National Science Foundation Public Access Repository | Journal of Librarianship and Scholarly Communication

Abstract:  Introduction: In 2022, the U.S. government released new guidelines for making publicly funded research open and available. For the National Science Foundation (NSF), these policies reinforce requirements in place since 2016 for supported research to be submitted to the Public Access Repository (PAR).

Methods: To evaluate the public access compliance of research articles submitted to the NSF-PAR, this study searched for NSF-PAR records published between 2017 and 2021 from two research intensive institutions. Records were reviewed to determine whether the PAR held a deposited copy, as required by the 2016 policies, or provided a link out to publisher-held version(s).

Results: A total of 841 unique records were identified, all with publicly accessible versions. Yet only 42% had a deposited PDF version available in the repository as required by the NSF 2016 Public Access Policy. The remaining 58% directed instead to publisher-held versions. In total, only 55% of record links labeled “Full Text Available” directed users to a publicly accessible version with a single click.

Discussion: Records within PAR do not clearly direct users to the publicly accessible full text. In almost half of records, the most prominently displayed link directed users to a paywall version, even when a publicly available version existed. Records accessible only through the CHORUS (Clearing House for the Open Research of the United States) initiative were further obscured by requiring specialized navigation of publisher-owned sites.

Conclusion: Despite having a repository mandate since 2016, NSF compliance rates remain low. Additional support and/or oversight is needed to address the additional requirements introduced under the 2022 memo.
