Why of global interest?Why of interest in computing?DefinitionsNSF Digital Libraries Initiative
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
Why of Interest in Computing? Next step in fields of DBMS, HT, IR, MM Efficiency requires advances in, e.g.,
– algorithms and data structures (ex., MPHF)– networking (ex., HTTP-NG)– OS (ex., support for streams)
Effectiveness requires advances in, e.g.,– AI (ex., multilingual texts, user adaptation)– HCI (ex., visualization, DLs embedded in activities)
CS Educ. can benefit; CS can aid Dist. Educ.
DLs: Definitions Super information systems KDI with persistence, organization, usability Libraries extended to include collections of digital objects
and to provide expanded services to distributed user communities without prior limitations of space, time, physical instantiation
Latest implementation of visions of Bush, Licklider, Nelson, and previous scholars
Systems, services, institutions, enterprises, and projects of the digital library community

Educating ALL future scholars so they can publish electronically and effectively use digital libraries (i.e., are Information Literate and can be more expressive)
Demonstrating how, for other organizations
What are we doing?
VISION,BENEFITS,
APPROACH,POSSIBILITIES
A Digital Library Case Study
Electronic theses and dissertations (ETDs)
Submission: http://etd.vt.edu
Collection: http://www.theses.org
Networked Digital Library of Theses and Dissertations (NDLTD) http://www.ndltd.org (formerly “National” because of Fed. funds, before international members started joining)
Something for EveryoneStudents - contribute -> gain acclaimUniversities - join -> help your students, gain
increased DL experience + visibilityResearchers - use, encourage -> contentPublishers - liaise, support -> have more
knowledgeable authors + backup detailsDL enthusiasts - adapt resources / ideas -> have
exemplary pilot / model project
What are the key ideas? People can switch to electronic documents
– Becoming more expressive with hypermedia Mandating ETDs will change all future
scholarship Scalability
– Empower authors to submit to DL, as a natural part of the educational process
– Study workflow & apply automation, so institutions streamline processing and build their part of the DL
– Federate along most suitable cultural/political lines
Key Ideas: Networked infrastructure
Scalability
Education is the rationale
University collaboration
Workflow, automation
Authors must submitMaximal access
PDF, SGML, MMStandards
Federated search
8th graders vs. grads
MARC, DC, URNs
What are the benefits?
Save students money Save handling, shelf space in libraries Build the Networked Digital Library of Theses and
Dissertations: with faster, broader, and less expensive access
Demonstrate how universities can work together directly (vs. indirectly through publishers or associations)
What are the long term goals? 400K US students / year getting grad degrees are exposed
/ involved 200K/yr rich hypermedia ETDs that may turn into
electronic portfolios Dramatic increase in knowledge sharing: lit. reviews,
bibliographies, … Services providing lifelong access for
students/researchers: browse, search, prior searches, citation links, ...
Record all work with NDLTD, return to prior situation, prepare bibliography
Powerful (multilingual, text, image) searching, browsing (with categories), following citation links
Support collaboration with others in same field: help with literature review, sharing tools and data sets, applying their methods
Undergraduate honors thesis: Todd Miller
Grad Student Assistant?
Increase local interchange among students, faculty, library, graduate school
Increase international understanding, building many more invisible colleges, with students more empowered
Connect graduate researchers with undergrads, who can access ETDs / them
Facilitate direct university collaboration, explicitly, in reshaping publishing world

Some Barriers at Universities
Lethargy; Not invented here (esp. large univ’s) Anger with unfunded, added, required work Last straw: using more frustrating technology Lack of experience in working together: graduate school,
library, computing staff Lack of interest in (quality of) student work More loyalty to discipline than campus Unwillingness to accept responsibility for growing
financial problems with libraries
SOLUTIONS, IMPLEMENTATION
Level 0 Involvement RISK FREE - allow students
Adobe Acrobat in bookstore Submission allowed (e.g., J. Daniels) Archive/access through UMI, Virginia
Tech, ... (Local) WWW site, publicity (Local) Assistance provided as
requested: email, phone, listserv(s)
Level 1 Involvement = Level 0 + LOW COST - help & encourage students
Install our software, change practices in graduate school and library
Train students Build grass roots support
– Advisory committee: representative? expert?– Champions to spread by word of mouth– Approval: Senates, Commissions, Deans, Students– Publicity to reach community
Level 2 Involvement = Level 1 + EVENTUAL FULL INVOLVEMENT
Require electronic submission Have firm arrangement with local library, OCLC,
VT and/or UMI re archival services Share MARC records, with URNs pointing to
archive copy (Stock laboratories) (Run servers: search, URN) (Launch evaluation program)
Support Services Developed
CD/WWW site with > 300M: student guidelines, listservs, FAQs, press info, multimedia training materials
Automated submission system SGML DTD for ETDs, SGML to HTML (web
generator) Donations: Adobe, Microsoft Evaluation: instruments, analysis
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 AAAS: Science wants first publication Textbook publishers: different market,
manuscript significantly reworked General: restricting access to local campus will
not cause any problems
Plans
Nurture federation -> summer workshop (now, in Memphis)
Increase # members -> lower barriers by supporting pilot efforts directly
R&D in federated fashion– USF: writing– UVA / U.Mich.: SGML– Portugal: national library requirements– Singapore: multilingual support with UNICODE
Summary
Sustainable, Scalable: started in 1987, growing, coupled with education
Open: everyone welcome, mutually agreed-upon standards, building international collaborative community
Content: valuable, high demand, aiming toward completeness
Usability: applying latest and future DL research so can easily submit, utilize
NDLTD Future Work 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

MHIA Workshops
ACM: SIGIR’96, MM’96, SIGIR’97-DL’97; IEEE CS: ICMCS’97, … (MM’98, Sept. in UK)
Aim: Curriculum Guidelines for MHIA Area New Programs, ex. Euro EI Masters Reusable WWW Knowledge Modules New Courses, ex. Hypertext, IR, Multimedia Add-ons to Existing Courses (Comparative
Languages, DBMS, HCI, Networking, OS)
Vision, Benefits, Approach Instead of building large, expensive multimedia packages,
that become obsolete and are difficult to re-use, concentrate on small knowledge units.
Learners benefit from having well-crafted modules that have been reviewed and tested.
Use digital libraries to build a powerful base of support for learners, upon which a variety of courses, self-study tutorials & reference resources can be built. (See NSF SMETE-Lib Study at http://www.dlib.org/smete/public/smete-public.html)
Concerns, Problems Motivating educators to create modules that can be
used elsewhere is difficult without a suitable reward structure and an infrastructure of testing, packaging, discovery, reuse, and evaluation.
There is a disconnect between researchers preparing exciting demonstrations for conferences and instructors interesting in helping students grasp underlying concepts and innovations in their area.
Solutions, Plans CSTC will have a variety of focused centers so that
different types of resources can be collected, tested, and suitably packaged:– laboratory exercises, activities, assignments
– visualizations and visualization tools
– interactive multimedia resources (CRIM)
ACM has been approached to launch a digital library “Transactions in Courseware and Education in Computing” to provide an ongoing infrastructure for CSTC.
CONCLUSIONS Digital libraries may provide powerful support for learners
if properly developed and supported by suitable, scalable, sustainable infrastructure.
NDLTD will have a dramatic impact on graduate education if institutions participate, which is a “win-win situation”.
CSTC and CRIM will help us explore how learning about computing can be enhanced by a large number of well-crafted modules that illustrate key concepts and can be “glued” together in a variety of fashions to suit local needs.
COLLABORATION ! NDLTD, CSTC, CRIM, NCSTRL, …
– Join and help build the collections
– Use the collections and their resources
– Help enhance the technology through R&D
Help solve key DL problems– Become a center (recall USF/English role in KDI)
– Connect with library/publishing world in Mexico
– Connect with preservation/dissemination in Mexico
– Work on testbed, system, or HCI aspects (DLI2)
