This workshop will focus primarily on the organizational and business issues around building a digital institutional repository. An institutional repository minimally meets four criteria • Institution-based • Scholarly material in digital formats • Cumulative and perpetual • Open and interoperable As background, this workshop will review the reasons behind the development of the DSpace service at MIT, including system development and the service and business models that served to move the project from research effort to a fully functional and integrated libraryservice. Although the business model we developed has MIT specific inputs, we find that many issues are common to all institutions that wish to develop an institutional repository service offering. For the purposes of organization, those issues can be grouped into • Implementation Planning • Legal and Regulatory Environment • Local Policy Development • Cost and Funding Models This workshop will focus on the business and organizational requirements for building sustainable institutional repositories, as opposed to the technical aspects.
