The National Audiovisual Center was established in 1968 to provide a single organizational unit that serves as a central information point on completed audiovisual materials and a central sales point for the distribution of media that were produced by or for federal agencies. This speech describes the services the center can provide users of audiovisual materials, whether government or the public, and the services the center can provide a producer of audiovisual materials within the federal government. The user information services are detailed in three separate categories: 1) a data bank of 10,800 federal audiovisual services; 2) the reference function; and 3) the publications function. (HAB)
