OUTLINE Introduction Global digital libraries, for education Building digital libraries NDLTD

– Overview, History– Members, Collection– Support, Extensions

CSTC, CRIM Conclusion

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).

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

NUDL

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, ...– Need tools & methods to make them easier to build

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)

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)

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

5S: Combinations

Societies + Scenarios = user model Societies + Scenarios + Spaces = user

interface Streams + Structures = markup Streams + Structures + Scenarios = object Structures + Scenarios = DBMS

Star Methodology

Neill Kipp Dissertation

Training interested groups about 5S and the Star Methodology, refining the Framework to have solid mathematical foundation

Case studies of projects at Virginia Tech or involving VT staff/students: CSTC, NDLTD, NARA (National Archives, with SAIC), Lexis, ...

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)

What are we doing?

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:

browse, search, prior searches, citation links

ETDs: Library Goals *Improve library services

–Better turn-around time –Always available

Reduce work –catalog from e-text –eliminate handling: mailing to UMI, bindery prep,

Archiving ETDs *

Every 15 minutes back-ups made of not-yet-approved submissions

Hourly back-ups of newly approved ETDs

Weekly back-ups of entire ETD collection

Copies stored on-site and off-site

VT ETD Cataloging * same as current cataloging policies, except:

– author-assigned keywords (not LCSH)– generic (not LC) call no.– fields/subfields as required for computer files– full abstracts

time savings– cataloger familiar with computer files– equipment, software for word processing– 5 minutes avg. (10-15 minutes for paper TDs)

Library Costs * $12/vol. for paper thesis processing

– catalog, bind, security strip, label, shelve– @950 vols./yr. = $11,466

$3.20/vol. ETD processing– cataloging @950 vols./yr. = $3040

$.07/vol. shelving $.04/vol. circulation

Costs/Savings at VT *

Graduate School stopped shipping to the library 3000 copies of paper TDs/year

Library stopped binding, shelving, and circulating 3000 copies of TDs/year

166 ft of shelf space saved/year by the library VT used existing equipment in Library (vs. start-up

costs for staff, hardware and software from from a zero-base estimate: $65,000 – see http://scholar.lib.vt.edu/theses/)

Dienst and Harvest - maybe MARIAN)

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

For professional societies

Like “writing across the curriculum” Besides writing: computing/communications,

information literacy, personal digital library management, tool use, research methods, collaboration, archiving/preservation

Data sets, communities of users of them Classification systems / browsing / searching NRC’s “On becoming a researcher”

SMETE Library -> NSDL(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

MARIAN

Multiple Access Retrieval of Information with Annotations

(Marian the Librarian …) Evolved from CODER system to a distributed

Online Public Access Catalog (OPAC), then DL backend, now becoming a full DL system

ENVISION

NSF “A User-Centered Database from the Computer Science Literature” (1991-93)

Collected bib/typesetter data, converted to SGML Scanned thousands of page images MARIAN search engine - can be made available (also

applied to the Virginia Tech library catalog) used as part of a prototype object-based DL, with tailored visualization interface (L. Nowell dissertation)

NSF Education Innovation (EI) NSF “Interactive Learning with a Digital Library in

Computer Science” (1993-98) 45 online courses (esp. Internet, IR, MM,

Professionalism, overall EI project pages): 100+K accesses/wk

Tools: SWAN (visualization), QUIZIT Evaluation

– traditional– network logging and analysis– tools for visualization

Digital Library Courseware

http://ei.cs.vt.edu/~dlib/ WWW pages or large PDF copy files Online quizzes based on book by Michael Lesk

(Morgan Kaufmann Publishers) Contents based on book, with several other popular

topics added (e.g., agents) Separate pages to supplement: Definitions,

Resources (People, Projects), and References

CS -> CSTC -> CRIM NSF and ACM Education Committee are funding a 2

year project “A Computer Science Teaching Center” - CSTC - http://www.cstc.org/

College of NJ, U. Ill. Springfield, Virginia Tech Focus initially on labs, visualization, multimedia Multimedia part is also supported by a 2nd grant to

Virginia Tech and The George Washington University: http://www.cstc.org/~crim/ (with curricular guidelines also under development)

Browsing (2)

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. (See NSF SMETE-Lib Study at http://www.dlib.org/smete/public/smete-public.html)
