The information sources most frequently used by students at the University of California, Davis, and the effectiveness of these campus resources among students, faculty, and staff members were surveyed using two mail questionnaires, which are appended. Responses were obtained from 364 student and 148 faculty and staff. Use of four different media was assessed: newspapers, radio, bulletin boards, and campus publications. Findings include the following: the most common information source for students was other students; the most popular forms of printed material used by students for campus activities and general information were the "California Aggie" and campus bulletin boards; students most often chose the "General Catalog" for academic and functional information; students did not always find printed material to be a satisfactory form of information transmission; students used campus publications to obtain activity information but not to determine where to go for counseling; differences in sex, class standing, and local residence had little effect on students' information-seeking behavior; students were often unsure about the difference between an adviser and counselor; and students were slightly more likely to select peer-operated services, while staff and faculty were somewhat more likely to select, or refer students to, the formal, staff-operated units. A bibliography is appended. (Author/SW)
