FAIRsharing record for: PubMed Unique Identifier

This FAIRsharing record describes: The PubMed Unique Identifier (PMID) is a 1- to 8-digit accession number with no leading zeros for managing and disseminating records at the PubMed repository. The PMID is a unique reference number for PubMed citations and is a distinctly different number from the PMCID and is used only for PubMed records. PMIDs are not reused after records are deleted. Prior to the 2004 version of PubMed (available December 3, 2003), many records contained a MEDLINE Unique Identifier in addition to the PMID. NLM no longer displays the MEDLINE Unique Identifier. The PMID has become the unique identifier for the MEDLINE record.
