PubMed

About PubMed: The MEDLINE database is widely recognized as the premier source for bibliographic coverage of biomedical literature. The PubMed version of MEDLINE includes the PREMEDLINE database, which provides very current basic citation information and abstracts before the full records are prepared and added to MEDLINE. New records are added to PREMEDLINE daily. In addition, for participating journals that are indexed selectively for MEDLINE, PubMed includes all articles from that journal, not just those that are included in MEDLINE. PubMed is also the literature component of the Entrez retrieval system for molecular biology information.
