The increasing availability of high quality digital texts and usage data about them provides opportunities to identify new uses for collections, alternative ways to present and explore content, and expanded audiences for the materials. Using this information and a rapid development model called a “flash build,” JSTOR is creating and partnering with other organizations to build new tools that add value to library investments in digital collections. Two examples are discussed: “Classroom Readings,” a tool designed to help educators find articles on JSTOR that are good candidates for teaching, and “Understanding Shakespeare,” a resource created in collaboration with the Folger Shakespeare Library that enables scholars to follow links in lines from Shakespeare plays to articles on JSTOR that reference them. The rapid development model used for these projects is easily reproducible and effective, and could be applied to many library-driven efforts.
