"Directly" funded means costs that can be identified specifically with a particular sponsored project, or that can be directly assigned to such activities relatively easily with a high degree of accuracy.
If a publication is in the journal section of the NLM catalog, NIH considers it to be a journal. Search the journal section of NLM Catalog (http://www.ncbi.nlm.nih.gov/nlmcatalog/journals) for the journal by title, title abbreviation, or ISSN. Automatic suggestions will display as you type. If the publication is not on the list, NIH will consider it a journal for policy purposes if it meets all of the following criteria:
You may also submit the manuscript to NIHMS upon acceptance for publication for a determination.
Final peer-reviewed manuscript: The Investigator's final manuscript of a peer-reviewed paper accepted for journal publication, including all modifications from the peer review process.
Final published article: The journal’s authoritative copy of the paper, including all modifications from the publishing peer review process, copyediting and stylistic edits, and formatting changes.
The NIH Public Access Policy implements Division G, Title II, Section 218 of PL 110-161 (Consolidated Appropriations Act, 2008). The law states:
The Director of the National Institutes of Health shall require that all investigators funded by the NIH submit or have submitted for them to the National Library of Medicine’s PubMed Central an electronic version of their final, peer-reviewed manuscripts upon acceptance for publication, to be made publicly available no later than 12 months after the official date of publication: Provided, That the NIH shall implement the public access policy in a manner consistent with copyright law.
PMID: Finds abstracts/citations in PubMed
PMCID: Finds papers PubMed Central (PMC)
PMIDs have nothing to do with the NIH Public Access Policy

A NIH Manuscript Submission Reference Number (NIHMSID) is a temporary substitute for a PMCID when using either Submission Methods C or D to post your paper. It is the # your manuscript receives when it is posted to the NIH.
Papers marked “In process at NIHMS” are only provisionally compliant within 3 months of the official date of publication. My NCBI will change the status to ‘Complete’ when a PMCID is issued. If the paper does not have a PMCID after 3 months, My NCBI will change the paper’s status to ‘non-compliant’ until a PMCID is issued.
