Latest Version of Emtree Introduces 930 New Terms

10. February 2017

The January 2017 version of Emtree, the thesaurus used in Embase, is now available on STN.

The Emtree thesaurus provides access to the terminology of pharmacology, biomedicine and medical devices. The new version adds 930 new terms to Emtree as preferred terms:

- 308 drug terms (terms assigned to the Chemicals and Drugs facet)
- 622 non-drug terms (terms not assigned as Chemicals and Drugs

In total, Emtree now includes 75,488 preferred terms and over 320,000 synonyms. Use Emtree as an aid to designing comprehensive yet precise searches. Be sure to check the Alerts you have running in Embase to determine if new Emtree controlled terms could improve your retrieval.
