The NCJRS Abstracts Database Thesaurus Term Search allows users to search for materials located in the Abstracts Database using an official NCJRS–controlled vocabulary. This controlled vocabulary is used to assign relevant indexing terms to the documents in the NCJRS collection. These indexing terms are located at the bottom of each abstract record in the Main Term and Index Term fields. See the record below for an example of "Main Term" and "Index Term."
This search looks only for terms listed in the Title field of the abstract record.

When a term is expanded, the results page will contain information specific to that term. If applicable and available, additional entries (e.g., Scope Note, Used For, Broader Term(s), Narrower Term(s), and Related Term(s)) will be provided.
The Scope Note entry defines or limits the specific use of a term. The Used For entry displays other concepts represented in the NCJRS system by the selected term. Broader Term(s) represent the higher, more general levels of a term's relationships, whereas Narrower Term(s) represent the lower, more focused levels. The Related Term(s) entry performs two functions: It provides alternative search terms and clarifies the scope of the expanded term.
