Embase is a biomedical literature database that provides comprehensive coverage of journal articles and conference proceedings. It indexes over 31 million records from over 8,500 journals. Embase focuses on literature relevant to disease, drug, and medical device research. It provides more extensive coverage than MEDLINE, including more non-English content and randomized controlled trials. Embase indexing uses a controlled vocabulary thesaurus called Emtree to deeply index articles at the level of drugs, diseases, and associated terms. This deep indexing allows users to precisely search and retrieve all relevant articles on a topic.
