Why this topic today?
Many users (patrons) prefer digital libraries to traditional libraries or the Web
Digital library collections often are free or less expensive, so are heavily used
Most publishers are working toward digital libraries to allow access to their content
Library and information science professionals are key players in building digital libraries

Licklider – Unified Theory?
Not ready in 1960s Analog – unified field theory in physics “Mess” today – segmented field, specialities
– Database <-> Knowledge <-> Content Mgmnt– Multimedia, Hypermedia, Hypertext– Logic, Algebra, Artificial Intelligence, …
Expensive, annoying for users– Don’t know where to look– Don’t know how to use services

Grand Challenges Can
Mobilize the community Spur creativity Lead to important benefits in society Push researchers to develop relevant theories Force people to work in teams/groups Convince funding agencies to invest Help bring about integration of systems,
interoperability, and seamless interfaces

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

Summarization
It seems that North Korea launch a missile againAfter North Korea launched a Daipodong missilelast month, NK is perceived to proceed to an additionaltest launch. Korea, US and Japan enter into an alertstate, and prepare for a joint response policy. Korea estimates that the additional launch will be on 09/05. Japan estimates that NK’s missile range is short. USinformation says that there is no sign of launch yet.

Presidential Directive - 12/17/1999Subject: Use of Information Technology to Improve Our Society
“13. The Secretary of the Smithsonian Institution, the Director of the National Science Foundation, the Director of the National Park Service, and the Director of the Institute of Museum and Library Services shall work with the private sector and cultural and educational institutions across the country to create a Digital Library of Education to house this country's cultural and educational resources.”

Vision
A Learning Environments and Resources Network for SMET
Education (LEARNS)
Designed to meet the needs of learners, in both individual and collaborative settings
Constructed to enable dynamic use of a broad array of materials for learning, primarily in digital format
Managed actively to promote reliable anytime - anywhere access to quality collections and services, available both within and without the network
![Page 60: Digital Libraries: Extending and Applying Information Science and Technology ProLISSA October 26-27, 2000 Edward A. Fox fox@vt.edu .](https://reader030.fdocuments.in/reader030/viewer/2022032604/56649e615503460f94b5c2e2/html5/thumbnails/60.jpg)
“The network is the library.”
![Page 61: Digital Libraries: Extending and Applying Information Science and Technology ProLISSA October 26-27, 2000 Edward A. Fox fox@vt.edu .](https://reader030.fdocuments.in/reader030/viewer/2022032604/56649e615503460f94b5c2e2/html5/thumbnails/61.jpg)
LEARNS Connects:
Users: students, educators, life-long learners
Content: structured learning materials; large real-time or archived datasets; audio, images, animations;primary sources; digital learning objects (e.g. applets);interactive (virtual, remote) laboratories; ...
Tools: search; refer; validate; integrate; create; customize; publish; share; notify; collaborate; ...
![Page 62: Digital Libraries: Extending and Applying Information Science and Technology ProLISSA October 26-27, 2000 Edward A. Fox fox@vt.edu .](https://reader030.fdocuments.in/reader030/viewer/2022032604/56649e615503460f94b5c2e2/html5/thumbnails/62.jpg)
Expectations of Tracks Core Integration: to coordinate a distributed alliance of
resource collection and service providers, and to ensure reliable and extensible access to and usability of the resulting network of learning environments and resources
Collections: to aggregate and actively manage a subset of the digital library’s content within a coherent theme or specialty
Services: to increase the impact, reach, efficiency, and value of the digital library in its fully operational form
Targeted Research: to have immediate impact on one or more of the other three tracks

CS Teaching Center (CSTC)
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.

Conclusions
Consider DLs (like the poetry project/paper) in South Africa
Education is one important application Cultural heritage, linguistic diversity, are important
to preserve Technology opens up exciting opportunities Having a framework and theory may lead to better
systems and broader applicability
