Medline Medline Produced by the U.S. National Library of Medicine, the MEDLINE database is widely recognized as the premier source for bibliographic and abstract coverage of biomedical literature. MEDLINE encompasses information from Index Medicus, Index to Dental Literature, and International Nursing Index, as well as other sources of coverage in the areas of allied health, biological and physical sciences, humanities and information science as they relate to medicine and health care, communication disorders, population biology, and reproductive biology.

Medline The Ovid MEDLINE database contains bibliographic citations and author abstracts from more than 5,200 biomedical journals published in the United States and in 70 other countries. The database contains well over 16 million citations dating back to the 1950. Although coverage is worldwide, most records are derived from English-language sources or have English abstracts. Abstracts are included for more than 75% of the records.

Related articles之功能 Each citation in PubMed has a link that will retrieve a pre-calculated set of PubMed citations that are closely related to the selected article. Click on Related Articles to the right of each citation to display the related set of articles. PubMed creates this set by comparing words from the title, abstract, and MeSH terms using a powerful word-weighted algorithm. Citations are displayed in rank order from most to least relevant, with the "linked from" citation displayed first.
