PMID is an acronym for PubMed Identifier which is a unique number assigned to PubMed citations of health science academic journal articles that are indexed by PubMed. It is used similarly to the International Standard Book Number (ISBN) for books.
As of 2005, there are roughly between 15-16 million numbers in use, starting from PMID 1, and about 1 million new numbers are added each year.

MediaWiki software recognizes inline PMID codes for life sciences and biomedical articles and automatically creates a search link to PubMed.
