1	Augmenting Library Services: Toward the Sharium INLS 235 Spring 2003
2	Outline Motivation: Why augment when there is so much to do already? DL research and development trajectory Focus on: Search and discovery Reference Contributions
3	First Principles: Libraries Libraries assess, collect, preserve, organize, provide access to information and promote its use to improve the human condition. Libraries are highly burdened to accommodate physical and electronic materials and increasing needs for information by larger and more diverse populations. Internet and WWW offer universal communication and publishing and challenge libraries to reconsider fundamental missions--DLs Leverage the DL challenge to develop a broader vision of information services for the common good: Sharium is a metaphor for this
4	First Principles: Information Seekers Information seeking is embedded in real life tasks People want/like to share altruism egocentrism investment (quid pro quo) peer pressure Innovation adoption is not a linear process
5	Digital Library Design Space
6	DL Missions DLs clearly must aim to collect, manage, and preserve electronic expressions of knowledge (this is a well-established mission). Knowledge is in people’s heads--DLs should aim to facilitate the use and development of the collective knowledge in human consciousness Human attention is a fundamental natural resource--DLs should provide tools and resources (material and expertise) to help optimize this resource
7	Sharium A virtual workspace with rich content and powerful tools where people can work independently or collaborate with each other to learn and solve information problems. A collaborative problem solving environment. Organized around resources and tools Encourages contributions and participation Is sustainable

14	Key Technical Challenges fostering and insuring quality control; transitioning information seekers from self-directed search to reference and community assistance when people do not succeed with self-directed approaches; developing layers of assistance from fully automated (e.g., FAQs), through community assistance (e.g., posting a question to a newsgroup), to professional assistance (e.g., online with a reference librarian), including hybrid solutions; and creating interfaces that do not overwhelm or frustrate information seekers as they transition through the various service layers.
15	Contributions Time (attention) Materials physical transfer (digitization, copy) rights agreements classification (metadata) validation/authentication
16	Key Technical Challenges Developing contribution mechanisms that allow people to easily digitize and/or transport objects; Managing content authority and quality; Insuring access (metadata formats; preservation and persistence; provenance).
17	Key Social Challenges Why do people share? Models? open source? Creation-ownership relationship Creating and maintaining trust Quality assurance Sustaining participation
