How is Embase indexed?

Fully indexed records in Embase (excluding MEDLINE records licensed from the National Library of Medicine) are manually indexed using the full text of each article. Index terms identified by trained indexers with a biomedical background are controlled against Emtree before being added to Embase records. Indexed records are available online within two weeks (on average) from receipt of the journal issue.

For licensed MEDLINE records, index terms assigned by the NLM from the MeSH thesaurus are mapped to Emtree.

Articles in Press, In-Process records, Preprints and Conference abstracts are automatically indexed based on title, abstract, and author keywords. From June 2024 onward, the same applies for reviews and short surveys, unless they are meta-analyses or systematic reviews (in which case they will continue to be manually indexed on full text).

Please refer to the Embase Indexing Guide for more information.
