"This thesaurus was designed for users of the Adult and Continuing Education Research Collection in Syracuse University (New York), which contains the archives of organizations and individuals central to the development of adult education as a field of study and practice. The thesaurus serves the historical and archival adult education materials of a specific place and is collection specific: the work represents the archive it serves. The thesaurus consists of three displays: conceptual, alphabetic, and rotated. The conceptual and rotated displays show only preferred terms (usable), whereas the alphabetic display consists of preferred and nonpreferred terms. The conceptual display indicates relationships among terms as they occur in the archive. The alphabetic display comprises the preferred terms, entry terms, scope notes, hierarchical relationships, and those of equivalence and of association. The rotated display indexes each word of both single and multiword preferred terms in alphabetical sequence."
