The idea of public library film circuits was first proposed by the Carnegie Corporation in 1947. In 1948, one of two three-year grants was given to the Missouri State Library for the development of a statewide film circuit. Film packages of four to nine films were circulated among eleven libraries. Early conflicts with the University of Missouri's film distribution system and problems with overspent grant funds were overcome. Policies were created and film packages were tailored to audiences. The project was a success at the grant's expiration in 1951. With growing enthusiasm (32 participating libraries) and state funding, the project continued as the Missouri Libraries Film Cooperative. In 1954, participating libraries took over funding the Cooperative, and by 1966, the number of films grew to 955. Serious problems with film maintenance threatened the Cooperative until 1966, when state funds were available. Now (1975), the total collection exceeds 3,800 films. Member librarians still pay, but now according to assessed valuation of the library and the population served. Film utilization, still considered a problem, is being overcome with workshops for members. An edited interview with the former director of the Missouri State Film Demonstration Project (1948-50) provides a personal view of early film circulation in Missouri. (DAG)
