The United States Government has recently endeavored to increase the accessibility of its scientific research for the general public. Many federal agencies have developed policies that are consistent with the open-access principles laid out by the “Holdren Memo” released by the White House Office of Science and Technology Policy in 2013a. Agencies have increased the accessibility of taxpayer funded research by developing open-access databases containing metadata and full-text downloads of scientific journal article publications. Our assessment of 10 such repositories across 19 federal research institutions finds that there is variability in the data that are stored, the accessibility of the data in these systems, and the integration of these systems with other commonly used research resources. This work serves as a useful resource for comparing open access efforts across federal agencies and understanding industry standards for publication accessibility.
