Conclusion
Digital Libraries --- Objectives
World Lit.: 24hr / 7day / from desktop Integrated “super” information systems: 5S: streams,
structures, spaces, scenarios, societies Ubiquitous, Higher Quality, Lower Cost Education, Knowledge Sharing, Discovery Disintermediation -> Collaboration Universities Reclaim Property Interactive Courseware, Student Works Scalable, Sustainable, Usable, Useful
DLs: Why of Global Interest? National projects can preserve antiquities and heritage:
cultural, historical, linguistic, scholarly Knowledge and information are essential to economic and
technological growth, education DL - a domain for international collaboration
– wherein all can contribute and benefit
– which leverages investment in networking
– which provides useful content on Internet & WWW
– which will tie nations and peoples together more strongly and through deeper understanding
DL Challenges
Preservation - so people with trust DLs
Supporting infrastructure - networks, ...
Scalability, sustainability, interoperability
DL industry - critical mass by covering libraries, archives, museums, corporate info, govt info, personal info - “quality WWW” integrating IR, HT, MM, ...

Conclusion
How to Build a Digital Library
Understand the problem (using the 5S
Framework)
Solve the problem (using the Star
Methodology)
– design, develop, evaluate,
– refine, operate
5S Layers
Societies
Scenarios
Spaces
Structures
Streams
Definition: Digital Libraries are complex systems that
help satisfy info needs of users (societies) provide info services (scenarios) organize info in usable ways (structures) present info in usable ways (spaces) communicate info with users (streams)
(see also latest issue of Information Processing and Management)
Definition: 5S Framework Societies: interacting people (, computers) Scenarios: services, functions, operations, methods Spaces: domains + constraints (e.g., distance,
adjacency): 2D, vector, probability Structures: relations, trees, nodes and arcs Streams: sequences of items (text, audio, video,
network traffic)
5S: Components
Societies: roles, rituals, reasons, relationships, artifacts Scenarios: acquire, index, consult, administer, preserve Spaces: physical, temporal, functional, presentational,
conceptual Structures: architectures, taxonomies, schema,
grammars, links, objects Streams: granularities, protocols, paths, flows,
turbulences

Conclusion
DLs --- Educational Implications Support distance education Level the playing field by giving everyone access to high
quality resources Enrich learning by giving access to primary rather than
secondary materials/objects Integrate simulations, visualizations, and multi-modal
presentations to enhance learning Allow learn-at-your-own-pace, ensuring success Allow specialized interfaces, or embedded DL for rich
support of learning activities
How do universities anddigital libraries relate?
Each U. will have its own digital library. Hence there will be large numbers (i.e., critical mass).
All students will learn how to use and how to “feed” digital libraries (and bring those habits to future work as needs and skills).
All digital library problems (esp. federation, flexibility, personalization) appear at U’s (so they are a good type of testbed, with willing collaborators in-place for developing solutions).
SMETE Library(from www.dlib.org)
Context: Global movement toward Digital Libraries (see April 1998 CACM)
NSF effort: Science, Mathematics, Engineering, and Technology Education Digital Library (focussed on undergraduates)– 3 workshops, yearly increasing funds / new calls
SMETE Library likely to operate as distributed federation, with separate parts for each key discipline, and to lead to a global effort

Conclusion
DLs: Broad Impact DLs should be in companies DLs should be in government (integrated) DLs should be built for all types of data, information, and
knowledge– covering knowledge management– covering data mining, IR, discovery, visualization– promoting specialized work on all types of collections for all types
of user groups DLs should encompass libraries, archives, museums, and
other institutions -- we can now store all data generated!

Conclusion
Relationship with publishers
Concern of faculty and students that still wish to publish books or journal articles, voiced: campus, Chronicle, NPR, Times
Solution: Approval Form gives students, faculty choices on access, when to change access condition; use IPR controls in DL
Solution: by case, work with publishers and publisher associations to increase access– AAP, AAUP– AAAS, ACM, ACS, Elsevier, ...
Some responses from publishers
ACM: need to acknowledge copyright Elsevier: need to acknowledge copyright IEEE-CS: endorse initiative ACS: After first publication, can release Textbook publishers: different market,
manuscript significantly reworked General: restricting access to local campus will
not cause any problems
Who are sponsors / cooperators? Funding, Donations of hardware/software
– SURA– US Dept. of Education (FIPSE)– Adobe Systems– IBM– Microsoft– OCLC
Others Serving on Steering Committee– National/Regional Projects: Australia, French
speaking group, Germany, IberoAmerica (ISTEC), UK (UTOG)
– CGS, National Lib. Canada, NSF, OAS, SOLINET, UMI, UNESCO, ...
How does this relate to UMI?
1987 UMI workshop to explore ETDs Support letter for US Dept. of Ed. proposal Steering and technical committee membership ProQuest Direct pilot of scanning works started

Note: All groups shown are connected with NDLTD.
Interoperability Tests Planned IBM DL: donated equipment, technical support,
powerful IPR (see TOIS, D-Lib) Z39.50: OCLC SiteSearch / VT tailored s/w
– university libraries w. catalogs of freely shared MARC records pointing to archival copies
– via URNs: handles & PURLs Dienst / NCSTRL - www.ncstrl.org: CS depts.,
DARPA, NSF, CNRI, Cornell - UVA is working on extensions for ETDs - Portugal is studying use for Europe - VT is working on Dienst to Z39.50 gateway
Access Approaches
Goal: Maximize access and services, e.g., by encouraging:
UMI centralized services Distributed service: Dienst, Z39.50 Regional services (e.g., OhioLink, AZ/NM) Local servers with browse, search
– From local catalogs to local archives WWW robot indexing and search services

Conclusion
Why might a university want to be involved?
To improve graduate education / better prepare your students / increase their knowledge and visibility
To unlock university information To save money for students and for the
university / improve workflow To build an important digital library
How can a university get involved?
Select planning/implementation team– Graduate School– Library– Computing / Information Technology– Institutional Research / Educ. Tech.
Send us letter, give us contact names Adapt Virginia Tech solution

Virginia Tech, ... (Local) WWW site, publicity (Local) Assistance provided as requested:
email, phone, listserv(s)
Type 2 Members University Agrees to Require ETDs
Like Type 1 but set date not reached Usually has an option or pilot May: wait for new AY; start with all who enter
after; … Build grass roots support
– Advisory committee: representative? expert?– Champions to spread by word of mouth– Approval: Senates, Commissions, Deans, Students– Publicity to reach community
NDLTD Members, Types 3-7
3. Part of university requires ETDs4. University allows ETDs5. University investigating, has pilot6. University consortium joins:
– CIC (Big 10 coordinating body)7. Non-university organization joins
– CNI (Coalition for Networked Info.)
Everyone LearnsStudents become “info literate”Students learn about discovery, search,
categorization/classification, e-pub, preservation, helping others find/reuse
Campus starts to think about IPR– e.g., Virginia Tech symposium
Faculty and students improve quality as reader base expands

Conclusion
Future Work - 1 of 2 Working with publishers to increase level of access as
much as possible Interoperability tests among universities and with UMI
to provide integrated services Study with testbed that emerges, to improve
information retrieval, browsing, interface, and other types of user support
Evaluation, improving learning experience, spread to worldwide initiative, sustainable support and coordination
Future Work - 2 of 2 Adding services currently prototyped
– annotation and SDI (routing) capabilities– Dublic Core metadata, crosswalk to MARC– support with IBM DL, OCLC SiteSearch
Adding other services planned– building and using citation database (w. SFX)– implementing plagiarism check (like “SCAM”)
Developing NUDL as a sustainable self governing global institution (w. committees) including active participation in Japan
