The specifications, planning, and initial development phases of the Random Access Center at the Oak Park and River Forest High School in Oak Park, Illinois, are described with particular attention to the ways that the five functional specifications and the five-part program rationale were implemented in the system design. Specifications, set out by a faculty committee prior to the contracting of the project, require instantaneous random access to both audio and visual materials, full user control over the selection and use of materials, remote access on the widest possible scale, and a single central storage and control facility. The goals of the program include enrichment of the program of studies; greater individualization of instruction in the curriculum; better integration of the instructional program around the focal point of the library; improvement of library services through the convenience and flexibility of an automated retrieval system; and finally, the elimination of the mechanical problems which inhibit student and teacher in their use of audio and visual materials.
