PubMed Reaches a Major Milestone
Database Adds 15 Millionth Journal Citation
PubMed, NLM's online retrieval service for citations for biomedical articles back to the 1950s, just reasserted its claim to the title "the world's largest biomedical database" by climbing to 15 million references. This milestone occurred August 11, 2004. The landmark citation was:
Zheng Y, Zhou ZM, Yin LL, Li JM, Sha JH.
Molecular cloning and characterization of a novel splicing
variant of PIASx.
Acta Pharmacol Sin. 2004 Aug;25(8):1058-64.
PMID: 15301740 [PubMed - in process]
PubMed citations are from MEDLINE and additional life science journals. Free online access to this resource was announced in 1997, when the database stood at approximately 9 million citations. More than 2.2 million searches of PubMed are conducted each day.
