PubMed, from National Library of Medicine, includes MEDLINE, PreMEDLINE, and other databases. The MEDLINE bibliographic database covers medicine, nursing, dentistry, the health care system, preclinical sciences, and veterinary medicine. More than 11 million bibliographic citations and author abstracts, back to the mid-1960's, from over 4,000 US and foreign biomedical journals. PreMEDLINE, an in-process database, gives basic citation information and abstracts before artcles are fully indexed with Medical Subject Headings (MeSH). New records are added daily tagged [MEDLINE record in process].
