1. Technology, Scalability, Metadata (or not) Research Challenges for Digital Libraries Carl Lagoze Cornell Information Science

2. Paradigm Mapping (or distorting!) Suppliers (Publishers) Intermediaries (Librarians) Consumers

3. Assumptions Clear definition of roles Feedback mechanisms are limited, well-defined, and mediated based on role Scale is an issue but not THE issue Control is important Collection boundaries are well-defined and distinct Users are mainly humans Expertise is proprietary

5. Assumptions Roles are fluid and ambiguous Scale is THE issue Anarchy is encouraged, control and order are overlaid Collection boundaries are fluid Machines and humans are users Everyone is a potential expert

7. Questioning Educational Impact Is access to resources the resources the solution? –The Web? –Google? What about quality? –Single measures? –Amazon, Epinions? How does it match current norms? –Chat? –Blogs? –Smart Mobs?

8. NSDL as it might be?
