University of Oslo Library (UBO) is today engaged in the creation and dissemination of knowledge. Our role has changed from manager of scholarly products to that of participant in the scholarly communication process. By setting up, promoting and managing an institutional repository the University of Oslo Library create a stable location where scientific information produced by the institute can be preserved and disseminated. The institutional repository is OAI-compliant. OAI-PMH (Open Archives Initiative - Protocol for Metadata Harvesting) defines a mechanism for data providers to expose their metadata. Service Providers use metadata harvested via the OAI-PMH as a basis for building value-added services. DUO – the e-print repository for the University of Oslo will be presented and demonstrated. The challenge in setting up an institutional repository is not a technology issue (although the problems of long-term preservation are very far from solved), but consists of managerial, organizational and cult ural issues. This paper will focus on the managerial, organizational and cultural issues.
