Citing PubMed Central (PMC) ID Numbers
When your manuscript is submitted to NIH, you will receive a NIHMS ID number, and once it is available in PubMed Central, it will be assigned a PMC ID number.Effective May 25, 2008, you will need to cite the PMC ID or NIHMS ID numbers for any of your articles that you cite in your progress reports, new applications, and renewals.
These are only needed for your articles accepted for publication on or after April 7, 2008, but you may include PMC ID numbers for articles already in PubMed or PubMed Central as well.
You can search PubMed Central for the citations, and the PMC ID numbers will be listed. The Medical Center Library can help you find these numbers, if you need assistance.
Please note: This is NOT the same as the PMID number found in PubMed. The PMC ID number begins with PMC and appears in the lower left of the PubMed citation in the Abstract display option.
If you publish through a journal in the list of Journals That Submit Articles To PubMed Central, you may indicate "PMC Journal - In Process" until the PMCID is available. There might be a slight delay in assignment of a PMCID even for those publishers working with NIH. By using this phrase, you are letting the NIH program officer know that your article will be in compliance with the new policy.
