Of the thirty-four librarians who offered information on the interface used for their digital audio reserves service, nineteen (56 percent) report that links to the audio selections are provided through a course management system, such as BlackBoard or WebCT. Seven (21 percent) use independent web pages, six (18 percent) use their online catalog and/or its reserve module.
Although none of the survey respondents report using Apple's iTunes software, we know from distribution-list postings and reports at conferences that some libraries provide listening assignments by maintaining a network-accessible shared ``library'' on iTunes.
