This collection of essays is a report of early findings from pioneers who have worked to establishdigital libraries, not merely as experimental projects, but as ongoing services and collectionsintended to be sustained over time in ways consistent with the long-held practices of print-basedlibraries. Particularly during this period of extreme technological transition, it is imperative thatprograms across the nation – and indeed the world – actively share their innovations,experiences, and techniques in order to begin cultivating new isomorphic, or commonly held,practices. The collective sentiment of the field is that we must begin to transition from apunctuated, project-based mode of advancing innovative information services to an ongoingprogrammatic mode of sustaining digital libraries for the long haul.
