The provision of equitable library services to distance learning students emerged as a critical area during the 1990s. Library services available to distance learning students included digital reference and instructional services, remote access to online research tools, database and research tutorials, interlibrary loan, and document delivery.

Previous studies evaluated traditional and telephone reference service; however, the literature lacked studies addressing asynchronous digital reference service. (Contains 2 tables.)
