ABSTRACT
Digital information is difficult to preserve for long-term access because of several factors: the dynamic nature of the content; the lack of libraries' clear rights and incentives to preserve content that is usually licensed; the effect of copyright extension on the roles and responsibilities for preservation; and the changing needs of the users. Several institutional responses to these challenges are discussed. [Article copies available for a fee from The Haworth Document Delivery Service: 1-800-HAWORTH.
