The NIH Public Access Policy is an open access mandate established by the National Institutes of Health in 2008. The policy requires scientists to make the results of their NIH-funded research publicly available in NLM’s digital archive, PubMed Central (PMC) within 12 months of publication. When publishing these results in a peer-reviewed journal, scientists must deposit the final manuscript of their articles in PMC.
