document: Library services today and tomorrow : lessons from iLumina , a digital library for creating and sharing teaching resources This article is based on the emerging experience associated with a digital library of instructional resources , iLumina , in which the contributors of resources and the users of those resources are the same-an open community of instructors in science , mathematics , engineering , and technology . Moreover , it is not the resources , most of which will be distributed across the Internet , but metadata about the resources that is the focus of the central iLumina repository and its support services for resource contributors and users . The distributed iLumina library is a community-sharing library for repurposing and adding value to potentially useful , mostly non-commercial instructional resources that are typically more granular in nature than commercially developed course materials . The experience of developing iLumina is raising a range of issues that have nothing to do with the place and time characteristics of the instructional context in which iLumina instructional resources are created or used . The issues instead have their locus in the democratization of both the professional roles of librarians and the quality assurance mechanisms associated with traditional peer review
