MIT Libraries and HP have released version 1.0 of DSpace (source available from sourceforge). DSpace is a digital repository in production use since September at MIT Libraries as a service for capturing, persisting, and providing access to the intellectual (research) output of the MIT community. DSpace will also be the long-term archive for materials from OpenCourseWare. Now it's available as an institutional repository platform to the rest of the world.
