Advances in audio technology in the 1980s and 1990s made it possible for librarians to create digital copies of sound recordings and to provide off-site access to them through streaming-media servers. Because streaming technology could accommodate heavy use at odd hours from any location, librarians quickly applied the new digital audio technologies to curricular listening assignments, providing a parallel to the print "e-reserves" projects developed by academic libraries during the 1990s. The results of a survey of thirty-nine digital audio reserves projects offers information on streaming formats, streaming rates, access control, user interfaces, staffing, equipment, and costs.
