These studies were conducted to determine whether the introduction of media services and materials in elementary schools previously without them had significant impact on the instructional programs of the schools. Within each study, information is organized under: (1) community background; (2) school background information that affects the school media program; (3) the instructional program; (4) the media center staff; (5) media center facilities and equipment; (6) materials; (7) expenditure for media center resources; (8) utilization and accessibility of materials; and (9) impact of the media center's program. Based on the reports of the interviewing teams and the responses of principals, media specialists, teachers and pupils interviewed, a summary makes recommendations for furthering the aims of the program. Appendices provide lists of popular material and a list of books in use which were published before 1960. (JY)
