A PMID is the unique identifier number used in PubMed for each article. The PMID is assigned to each article record when it enters the PubMed system. An "in press" publication will not have one unless it is issued as an electronic pre-publication. The PMID# is always found at the end of a PubMed citation. PMIDs do not change over time or during processing and are never reused.

Example of PMID#: Diehl SJ. Incorporating health literacy into adult basic education: from life skills to life saving. N C Med J. 2007 Sep-Oct;68(5):336-9. Review. PubMed PMID: 18183754.

This library guide is to tutorials on how to use PubMed.

To search in PubMed by PMID, enter the ID with or without the search field tag [pmid]. You can search for several PMIDs by entering each number in the search box separated by a space (e.g., 17170002 16381840); PubMed will or the PMIDs together. To search in combination with other terms, you must enter the search field tag, e.g., lipman[au] 16381840[pmid].

A similar number is the PMCID, which is the unique identifier number used in PubMed Central. People are usually looking for this number in order to comply with the NIH Public Access Regulations. A PMCID# is assigned after an author manuscript is deposited into PubMed Central. PMCID#s can be found at the bottom of an article citation in PubMed, but only for articles that have been deposited in PubMed Central.
