In the United States, federal government directives, such as the White
House Office of Science and Technology Policy Holdren (2013) and Nelson
(2022) issued memos, have mandated that research funded by tax-dollars must
be made freely available to the public. In the wake of these mandates, and
building on previous studies (Hudson Vitale et al., 2017; Johnston &
Coburn, 2020), we launched a research and advocacy project to better
understand the role of institutional repositories (IRs) and institutional
data repositories (IDRs) in data sharing among Association of Research
Libraries (ARL) member institutions.
