MEDLINE® UI Index Discontinued in PubMed®

MEDLINE UI Index Discontinued in PubMed. NLM Tech Bull. 2006 Sep-Oct;(352):b1.

October 06, 2006 [posted]

MEDLINE Unique Identifier (UI) will no longer be searchable in PubMed when the 2007 PubMed system becomes available in mid-December of this year. The PMID continues to be the unique number assigned to all PubMed records.

The MEDLINE UI/PubMed ID Matcher utility will continue to be available to users. [Note: The MEDLINE UI/PubMed ID Matcher was discontinued in July 2007].
