There's an interesting - and rather discouraging - article in the Chronicle of Higher Education today that discusses how troves of old recordings are hidden away on campuses and are degrading into unusability because archivists aren't aware of what they have. "At research universities across the country, archivists are painfully aware that large portions of their institutions’ audiovisual legacies are in decay. Old formats must be digitized if they are to be used, but first they must be identified and salvaged." The article cites to a census that was conducted recently at the University of Illinois at Urbana-Champaign - a census that turned up 408,000 items in 101 locations on the campus. These included rare 1920s films; caches of ethnomusicology field recordings; videotaped supercomputer animations; audiotapes for speech-recognition research; film documenting the Nobel laureate Paul Lauterbur’s work on magnetic resonance imaging; and a sociologist's painstakingly indexed film collections of 1960s protests. A similar census at Indiana University turned up 600,000 audio, video, and film items, in 50 formats that require digitization and preservation.
