Thesaurus
The thesaurus is a list of pre-defined terms and related synonyms, or ‘controlled vocabularies’, used in a specific context. These terms are used to register and search for information in the BCH databases. A preferred use term in the controlled vocabulary is the term selected from among synonyms to be used for indexing and retrieval purposes. For example, maize is the preferred use term over corn in the BCH. To access the thesaurus, please
