Why of global interest?
Why of interest in computing?
NSF 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

Core Sponsors: NSF, DARPA, NLM, LoC, NASA, NEH
  ~$8-10 million/yr for 4-5 years (beginning FY98)
  sponsor a full-spectrum of activities
   – fundamental research, content & collections development, domain applications,
     testbeds, operational environments, new resources for education and preserving
     America’s cultural heritage

  address topics over entire DL lifecycle
   – information creation, dissemination, access, use, preservation, impact, contexts

  implement a modular, open program structure
   – add new sponsors, performers, projects at any time

Program Goals: new DL research, technologies and applications to advance
the use of distributed, networked information of all types around the nation and the world

   Funding and Launch Full-Scale
       Program of Support for
     International Collaborative
    Activities in Digital Libraries
        Beginning in FY 1999
          Goals for the Future
 Gather information and build collections
  (to understand the incompleteness of our knowledge)
• Create new communities
  (to communicate and collaborate)

• Make technology disappear

          What are we doing?
Aiding universities to enhance grad educ.,
publishing and IPR efforts: to help improve
the availability and content of theses and
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
   A Digital Library Case Study

dissertations (ETDs)    Dissertations (NDLTD)
Submission:          (formerly “National”
                        because of Fed. funds,
Collection:             before international   members started
      Something for Everyone
Students - contribute -> gain acclaim
Universities - join -> help your students,
gain increased DL experience + visibility
Researchers - use, encourage -> content
Publishers - liaise, support -> have more
knowledgeable authors + backup details
DL 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
– 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      University collaboration

                 Workflow, automation

                 Education is the rationale
                      8th graders vs. grads
                     Authors must submit
Maximal access
                      PDF, SGML, MM
                      MARC, DC, URNs
                      Federated search
    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, ...
     Grad Student Assistant?
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
            Social Capital?
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
How are ETDs being done at
      Virginia Tech?

Some produced w. SGML (XML)
Most produced using standard word
processing packages as PDF files

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
    Level 0 Involvement
   RISK FREE - allow students

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
–   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
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
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

    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
         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.
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.
– 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)
