In some communities, commercial activity by the local university is perceived as a threat to the reciprocity of the "town-gown" exchange relationship. This study was designed to provide an information base from which negotiations in this area could proceed. Students (N=200) and faculty/staff (N=100) at the University of Maryland, College Park, were surveyed about their use of university (student union) and community-based commerical operations, with 108 students and 59 faculty/staff responding. It was found that respondents used services in the Stamp Student Union and the local community of College Park with similar frequency, although the student union was used more often than local business establishments for its restaurants and convenience store, restroom facilities, and the tenant University Book Center. Discussion focuses on the ways in which these research findings were used to promote better "town-gown" relations, and recommendations based on the findings are offered. Tables are appended. Fifteen tables are provided. (TE)
