10.0 Term relationships
Three types of relationships are represented in the cross- reference structure of Library of Congress Subject Headings: equivalence, hierarchical, and associative. These relationships are expressed in terms of USE, UF (Used for), BT (Broader term), NT (Narrower term), RT (Related term), and SA (See also) references. Each reference links a term or heading with another heading or with a group of headings.
