- Looking at Digital Library Usability from a Reuse Perspective. Sumner, Tamara Dawe, Melissa Computer System Design Educational Resources Electronic Libraries Information Dissemination Information Services Information Sources Information Systems Shared Resources and Services User Needs (Information) The need for information systems to support the dissemination and reuse of educational resources has sparked a number of large-scale digital library efforts. This article describes usability findings from one such project--the Digital Library for Earth System Education (DLESE)--focusing on its role in the process of educational resource reuse. Drawing upon a reuse model developed in the domain of software engineering, the reuse cycle is broken down into five stages: formulation of a reuse intention; location; comprehension; modification; and sharing. Using this model to analyze user studies in the DLESE project, several implications for library system design and library outreach activities are highlighted. One finding is that resource reuse occurs at different stages in the educational design process, and each stage imposes different and possibly conflicting requirements on digital library design. Another finding is that reuse is a distributed process across several artifacts, both within and outside of the library itself. In order for reuse to be successful, a usability line cannot be drawn at the library boundary, but instead must encompass both the library system and the educational resources themselves.
