International biomedical database of journal articles, with bibliographic descriptions, abstracts, descriptors (MeSH-headings) and references to the full-text availability on the Internet (although not always accessible). There is an emphasis on clinical literature and American biomedical literature. PubMed (=Medline expanded) contains references to journal literature from 1950 to the present and now amounts to more than 32 million records. PubMed now includes OldMedline with articles from the Index Medicus and published between 1953 and 1965. PubMed is updated every week.
Records of articles which are full-text available on the Internet contain a full-text link. Unfortunately, not all links provide access, because of license restrictions.
