Audiovisual archive
An audiovisual archive is concerned with the preservation and access to films, videos, audio recordings, images, television, radio, and other audio and visual media, rather than written documents. In addition to media, it distinguishes itself from other forms of archiving by having its tradition of theory, a body of research, principles, vocabulary, and unique skills, as well as specific sets of standards to follow. Changes in technology create challenges with cost, access, preservation, and training.
