Abstract
This chapter describes the expression of relationships in a traditional library subject heading system, Library of Congress Subject Headings (LCSH). Following an introductory section an the history and scope of LCSH, information is presented an its reference structure, documentation, and notation. The development and current use of references to express equivalence, hierarchical, and associative relationships are discussed. Other relational devices, such as scope notes and Library of Congress Classification numbers, are also covered. Changes to improve the reference structure of LCSH and facilitate its use in online catalogs are reviewed.
