Attitudes and behavior of students and employees at The University of Maryland, College Park, regarding the Maryland Student Union (MSU) were surveyed. The typical respondent was a single, white, undergraduate female, who commuted to school and was likely to use the MSU approximately four times a week. There was a generally positive attitude toward the MSU among students and employees. The MSU was viewed as a facility where students (more than employees) could go to meet with friends. International and black undergraduates were more likely to feel this way than were graduate students. After 7:00 p.m. during the week was the most convenient time for most respondents to attend MSU programs; films (40 percent), arts and crafts fairs (36 percent), and games and tournaments (20 percent) were the programs attended by the largest percentages. The textbook store, fast food restaurant, rest rooms, bulletin boards, the movie theater, and the information center were the resources used by the largest proportion of individuals. The wide use of information and publicity services such as the bulletin boards, the information center, and the school newspaper dispenser highlights the role of the MSU as an information exchange for the campus. These services were likely to have a greater frequency of use by MSU patrons than other services. International students tended to differ most often from the other groups in the use of food services; they use the food services at the MSU more frequently for breakfast, lunch, and snacks. (SW)
