This discussion of several of the issues and systems of videodisc technology as applied to the library, information, and instructional sciences is based upon the Utah State University Videodisc Innovation Projects. Descriptions of the major marketed videodisc systems, as well as those soon to be marketed, are given. A critique of the ABC/NEA Schooldisc Program is also included. A 72-item list of references and selected bibliography is provided, which includes references dealing with fault tree analysis (sometimes referred to as "fault free analysis") as a recommended tool to assist with the smoothing out of the diffusion process for videodiscs. Library, information, and instructional specialists are seen to be in a position to play a major role in that diffusion process. (Author/LLS)
