Because of a need for information about the structure, staffing, physical space, and types of activities of media service departments at colleges and universities, a study was conducted to gain a snapshot of media service programs at 4-year institutions with student enrollments between 5,000 and 10,000 students in 1992 and 1993. A 47-item questionnaire was mailed to media service departments at 141 institutions, and completed questionnaires were received from 90 colleges or universities (64 percent). A typical media service department would be housed in one location and administered by a full-time director with 6 to 10 years of experience. One additional professional and 10 to 15 students would comprise a typical staff. Typical support to instruction would include maintenance and circulation of a video and film collection, with associated services that could include video production and reception as well as photography and film processing. Recommendations are made for studying media services at other types and sizes of institutions. One figure and three tables present study findings. (Contains 5 references.) (SLD)
