MEDLINE is an extensive database of life sciences and biomedical information. It includes most major, peer reviewed medical and health journals. It is published by the American National Library of Medicine.

It covers all literature published from 1966 to the present day. It also contains some selected literature prior to 1966. Currently over 5,200 journals in around 40 languages are included. 

MEDLINE is a key part of the search engine PubMed. PubMed allows users to search MEDLINE and gives free access to the publication details, abstracts of papers and where available links to free electronic full-text articles. PubMed comprises more than 36 million extracts from MEDLINE, life science journals and online books.

The MS news and research updates on the MS Trust website include links to Medline abstracts of the papers reviewed.
