"The approximately 1,300 terms in this thesaurus come from many sources; before weeding, there were nearly 5,000 seed terms that originated in several existing controlled and uncontrolled vocabularies. A few terms have been added by the editor to fill obvious omissions in the hierarchy, and reference has been made both to the Education Resources Information Center (ERIC) thesaurus and to Helen Willa Samuels’s Varsity Letters for enlightenment and clarity, although neither of these sources was incorporated. LCSH is the preferred term unless the editor found a strong sense of the term's abandonment in contemporary usage by comparing the LCSH term with the terms used in the other thesauri. Some terms may inspire controversy; in such cases the policy of preferring LCSH over other terms was the rule. Submission of the terms in this thesaurus as new terms or as cross- references to the Library of Congress through the Subject Authority Cooperative Program of the Program for Cooperative Cataloging (SACO) are encouraged.
This thesaurus is a set of terms for use by any college or university archives in the United States for describing its holdings."
