The NIH Policy experts recommend you contact the journal and request permission to upload the final published article (i.e. the PDF available on the journal website). Once you have the rights, you can upload this version to the NIH Manuscript Submission system (NIHMS). Contact the NIH Public Access Policy Help Desk if you have further questions.
The NIH Public Access policy stipulates that publications must be made available to the public in PubMed Central no later than 12 months after publication. However, this does not mean that you have 12 months to submit your publications. Articles should be submitted upon acceptance for publication in order to ensure that all submission tasks are completed within 3 months of the official publication date. If you need to cite your publication on a progress report, you will need to use the PMCID or appropriate substitute to demonstrate your compliance with the Public Access Policy, even if the article was recently published (See Show Compliance page in this guide).
