The NIH Public Access Policy ensures that the public has access to the published results of NIH funded research. It requires scientists to submit peer-reviewed journal articles that arise from NIH funds to the digital archive PubMed Central. The Policy requires that these articles be accessible to the public on PubMed Central to help advance science and improve human health.
If your article was accepted on or after April 7, 2008, you must submit your manuscript to PubMed Central. NIH has a thorough FAQ that can answer many questions, as well as tutorials that can show you how to comply. If your article was accepted for publication before April 7, 2008, or is based on research funded by a grant that expired in FY 2007 or earlier, the NIH Public Access Policy does not apply.
Applications, proposals, or progress reports to NIH must include the PubMed Central reference number (PMCID) when citing articles that arise from the submitting PI's NIH funded research.
How to comply
In all cases, the PI is responsible for ensuring compliance with the NIH Public Access Policy.
