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.

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.
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 list below only shows selected journals.
