<!doctype html public «-//w3c//dtd html 4.0 transitional//en»> http-equiv=content-type> Every year vast numbers of valuable sound recordings, films, and videos housed in public collections are unintentionally damaged or destroyed because of a lack of basic knowledge about how to properly handle these materials. Many audiovisual collections are not being stored properly and are inaccessible due to the lack of appropriate playback technology and technical expertise. The book Preserving Audiovisual Document Collections offers guidance to non-specialized workers in archives, libraries, and museums about how to properly handle, safeguard, and improve accessibility to their audiovisual collections.
