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

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

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
![Page 50: Networked Digital Library of Theses and Dissertations (NDLTD - ) 15th Digital Library Workshop (DLW15) - Nara, Japan July 19, 1999](https://reader036.vdocuments.us/reader036/viewer/2022081520/5697bf821a28abf838c85e57/html5/thumbnails/50.jpg)
Why might your 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

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, ...
![Page 70: Networked Digital Library of Theses and Dissertations (NDLTD - ) 15th Digital Library Workshop (DLW15) - Nara, Japan July 19, 1999](https://reader036.vdocuments.us/reader036/viewer/2022081520/5697bf821a28abf838c85e57/html5/thumbnails/70.jpg)
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
![Page 71: Networked Digital Library of Theses and Dissertations (NDLTD - ) 15th Digital Library Workshop (DLW15) - Nara, Japan July 19, 1999](https://reader036.vdocuments.us/reader036/viewer/2022081520/5697bf821a28abf838c85e57/html5/thumbnails/71.jpg)

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
![Page 74: Networked Digital Library of Theses and Dissertations (NDLTD - ) 15th Digital Library Workshop (DLW15) - Nara, Japan July 19, 1999](https://reader036.vdocuments.us/reader036/viewer/2022081520/5697bf821a28abf838c85e57/html5/thumbnails/74.jpg)

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)
![Page 76: Networked Digital Library of Theses and Dissertations (NDLTD - ) 15th Digital Library Workshop (DLW15) - Nara, Japan July 19, 1999](https://reader036.vdocuments.us/reader036/viewer/2022081520/5697bf821a28abf838c85e57/html5/thumbnails/76.jpg)
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) (5 Element System: Fire, Wood, Earth, Metal, Water)
![Page 77: Networked Digital Library of Theses and Dissertations (NDLTD - ) 15th Digital Library Workshop (DLW15) - Nara, Japan July 19, 1999](https://reader036.vdocuments.us/reader036/viewer/2022081520/5697bf821a28abf838c85e57/html5/thumbnails/77.jpg)
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
![Page 78: Networked Digital Library of Theses and Dissertations (NDLTD - ) 15th Digital Library Workshop (DLW15) - Nara, Japan July 19, 1999](https://reader036.vdocuments.us/reader036/viewer/2022081520/5697bf821a28abf838c85e57/html5/thumbnails/78.jpg)
5S: Combinations
Societies + Scenarios = user model Societies + Scenarios + Spaces = user
interface Streams + Structures = markup Streams + Structures + Scenarios = object Structures + Scenarios = DBMS

Open also to study DL projects elsewhere Focusing too on the design artifacts developed and related
issues of efficient description and representation (esp. with markup, hypermedia)

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
![Page 83: Networked Digital Library of Theses and Dissertations (NDLTD - ) 15th Digital Library Workshop (DLW15) - Nara, Japan July 19, 1999](https://reader036.vdocuments.us/reader036/viewer/2022081520/5697bf821a28abf838c85e57/html5/thumbnails/83.jpg)
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
