PMCIDs must be included when citing papers in NIH applications, proposals, and reports.
- If the paper was published more than 3 months before an application, proposal, or report is submitted, the PMCID must be used.
- If the paper is in press or published within 3 months of the application, proposal, or report submission, PMCID may be used. Alternate acceptable documentation:
- "PMC Journal – In Process" – for final published articles being submitted by the journal or publisher
- NIH Manuscript Submission System reference number (NIHMSID) – for final peer-reviewed manuscripts submitted by the author
- When the article is submitted by the journal publisher, it will not receive a NIHMSID, but will first have the "PMC Journal - In Process" status and then a permanent PMCID.
- When the article is submitted by the author, it will receive a temporary NIHMSID that will later be replaced by a permanent PMCID.
Either the NIHMSID or the PMCID are acceptable for proof of policy compliance within the first 3 months after publication. After that, the PMCID must be used. The PMCID always supersedes the NIHMSID.
