For the most up-to-date listing of open-access journals, the Directory of Open Access Journals (DOAJ) site provides a directory of thousands of open-access journals.
For the most up-to-date listing of open-access books, the Directory of Open Access Books site provides a directory of thousands of open-access books.
The American Geosciences Institute (AGI) also provides a listing of open-access journals that GeoRef covers. Their listing only shows journals that appear to be stable, as well as a continual plan to remain open. Journals that require subscriptions to current issues are not included in their list.
The U.S. National Science Foundation's Public Access Initiative ensures the outputs of NSF-funded scientific research are made publicly available to the greatest extent, with the fewest constraints possible and consistent with law.

NASA's Public Access Plan was released January 6, 2025.
The full report can be found here: https://www.nasa.gov/nasa-science-policies-and-reports/
The updated plan highlights:
Requires scientific data underlying publications to be made freely available and publicly accessible by default at the time of publication.
The data must also have a persistent identifier, use metadata standards, and be shared in a repository designated by the appropriate NASA program or meet the guidelines provided by the Desirable Characteristics of Data Repositories for Federally Funded Research.
Requires peer-reviewed publications and the associated metadata to be made freely available at the time of publication in NASA's designated repository, PubSpace.
Researchers can either submit their accepted manuscripts directly to PubSpace or publish with a journal that has an agreement with NASA to deposit the Version of Record in PubSpace (e.g., journals that are part of CHORUS).
Requires scientific software underlying peer-reviewed publications or used to support data analysis to be made freely available and publicly accessible by default at the time of publication.
