This thesaurus was compiled to make the materials in the Patient Education Room of the Donald J. Vincent Medical Library at Riverside Methodist Hospital, Columbus, Ohio, more accessible to patients. Subjects are grouped in fairly broad categories (e.g., Aging & Problems of Aging; Alcohol & Alcohol Abuse; Careers in the Medical Field; Childhood and Childhood Problems; Domestic Violence, Child Abuse & Sexual Assault; Infectious Diseases; and Reconstructive & Plastic Surgery). Main subject headings are in all capital letters. Cross references (USE, USED FOR, and RELATED TERM) are included as often as possible. General classifications of books on each subject and titles of videocassettes available to patients and their families are included. Each pamphlet or brochure in the collection has been marked with a two or three letter alphabetic code to aid in reshelving. This document may aid others in organizing a collection of medical information for easy access by the public. (THC)
