4. PMID number The PubMed Identification (PMID) number can save you time. The PMID identifies one specific article and is located at the bottom of every PubMed reference. View Example.

When the PMID Helps:

• If you have a print out of PubMed references and want to easily pull them up again.
• If you need to remember a citation later, but don't have time to write down the reference.
• If you want to pull up references in PubMed that you found in another database. Some databases, in particular UpToDate, list PMIDs in their references.

Simply type (or copy/paste) the PMID number into PubMed's search box to retrieve the reference.
