Research products falling under the policy must be deposited with NSF through Research.gov before they can be included in NSF project reports.
The NSF's public access policy applies to research resulting from awards submitted or due after the effective date of January 25, 2016.
Note: If you are familiar with the NIH Policy, this is a departure in that conference proceedings are included under NSF's, though not under NIH's policy.
The article or proceeding must be in compliance by the time a project report is submitted or it can not be included in the report. You can deposit the manuscript while compiling the report. NSF indicates that after deposit the process of validation will take no longer than six hours.
There is a publisher-determined "administrative period" (embargo) of up to 12 months that applies to deposited works. NSF (with publishers) determines and manages this period. You will not be asked to report this.
You must submit a PDF/A version of the paper, either way.
The version submitted may or may not be the one made available to the public, depending on publisher policies. It WILL be available to PIs, Co-PIs, and NSF Program Staff after the project report is submitted.
Manuscripts must be deposited through the Research.gov site. Only the PI or co-PI can deposit these materials.
Submission can be done from Research.gov in two ways
