Today’s Agenda
• Historical examples
• An architectural way of looking at the territory
• Current examples at my institution
Millman—Nov 04—3
Dig Lib History—1
• non-networked: CD’s, videodisk (’80s)• networked
– ftp, simtel-20 “archive”– campus-wide information systems
• NSF DLI “1” awards (1994)– monolithic systems– comprehensive systems– document processing– architectures– formats (video, GIS, SGML text)
• Industry initiatives (mid ’90s)– web site as public presence– unmediated technical libraries– search engines
Millman—Nov 04—4
Dig Lib History—2• Digital Library Federation (1995)
– initially “a dozen” research libraries– provide leadership
• NSF DLI “2” awards (1999)– many smaller projects– independent technology & content
• Libraries common practices– metadata focus– separation of objects from processes
• Industry and higher-ed common practices– workflow / CMS– learning management systems– institutional repositories– archives

Interface Activity
• application categories
• delivery platforms
Millman—Nov 04—18
Local Examples
• Electronic Publishing Initiative at Columbia (EPIC)– collaboration among libraries / technology / university press– experiments in workflow, sustainability, infrastructure
• Columbia Center for New Media Teaching and Learning (CCNMTL)– innovation in networked learning– strong teaching faculty engagement
• Department of Computer Science– integrated retrieval strategies– media formats
• Libraries Digital Program– collections– discovery tools
