Unit 14: ERIC and Thesaurofacet

The Broader Term (BT) is the mandatory reciprocal of the NT. Broader Terms include as a subclass Notes
the concept represented by the main (narrower) term.

Sometimes a term may have more than one Broader Term:

In ERIC, computer searching of a Broad Term will not automatically retrieve documents
representing the concepts of its Narrower Terms, unless those NTs have also been
assigned to the documents in indexing (e.g., searching LIBRARIES will not automatically
also retrieve literature on SCHOOL LIBRARIES or any of the other NTs to LIBRARIES).
To search automatically the broad term and all its narrower terms, use the Explode
function.

RT (Related Term)

Related terms have a close conceptual relationship to the main term, but not the direct class/subclass
relationship described by BTs/NTs. Part-whole relationships, near-synonyms, and other conceptually
related terms, which might be helpful to the user, appear as RTs.
