What Is a Digital Library?
An information system providing network access
to organised digital collections, containing
primary documents
Digital collections:
–   Full text (e.g. books, journals)
–   Images (e.g. photographs, scanned pages)
–   Graphics (e.g. charts, drawings)
–   Animations (e.g. cartoons)
–   Audio (e.g. music)
–   Video (e.g. movies, lectures)

 What is a Digital Library?

Synonyms: Electronic library, Virtual
Automated library with materials in
physical form, OPACs and bib.databases,
on their own, do not constitute a DL

What about linking citations to full text
(e.g. Silver Linker)? Is that not a DL?

               January, 2000                4
Impetus for DL Development
Internet and the World Wide Web
Inexpensive, high capacity digital storage
Digitization hardware & software
Digital document formats
DL projects:
–   NSF/NASA/DARPA DL Initiative (1994)
–   TULIP project (1993-96)
–   USA, Europe, Australia, New Zealand, Singapore,

Global DL?

      Some DL Examples
NCSTRL - Networked Computer Science
Technical Reports Library (
NDLTD - National Digital Library of Theses
and Dissertations (
New Zealand Digital Library (
CORR – Computing Research Repository

              January, 2000                  7
Let’s take a look at a few

         January, 2000       8
What Features Do We See?
Structured access
Browse and search features appropriate to
the content
Importance of metadata, as approach to
the digital document
Distributed digital collections –
transparent access
Submission support, alerting services

              January, 2000                 9
      Advantages of DLs

Search for any word or phrase
Access from anywhere, anytime
Copy without errors
Less physical space
Improved services
Better preservation and conservation (do
not decay with time)
Cost efficiency

              January, 2000                10
          Some Limitations
Reading discomfort
Lacks support for ‘chance discovery’ associated
with browsing of physical material
Restrictions on usage
– Ownership and open access enjoyed by libraries and library
  users will be challenged
– Licensing, pay-per-use models
DLs will need regular refreshing of stored

                    January, 2000                              11
           Key Challenges
Disparate content formats
Interface design
Maintenance (workflow, responsibilities, training)
Naming and identification of digital documents
(e.g. DOI, PURL)
Rights management & Authentication
Content creation
Multilingual issues
Metadata standards

                 January, 2000                       12
Document Object Identification

         Indian Situation

No past, we have only future!
A few, random attempts (IGNCA, C-DAC,
IISc, etc.)
There is tremendous interest in setting up
Perception problem:
– DL is often thought of as a replacement of the
  conventional library!
– Nothing wrong with the idea, but impractical

                 January, 2000                     15
        Indian Situation…
There will be increasing compulsions for
DL efforts
– Digitization of intellectual content generated
  internally (e.g.: reports, theses, faculty publications)
– Improved access to internal information (‘Access to
  the corporate memory’ – Verity)
– Local archiving of licensed electronic publications
  (e.g. electronic journals)
– Hosting of Indian journals

                   January, 2000                             16
       Indian Situation…

Current solutions
– Integration using freeware on intranets
     Requires local system level expertise
– Integrated, commercial software (e.g. IBM DL)
     Expensive, complex
     Lack of support
– Extension of library automation packages to
  support DL
     Poor architecture
     Scalability issues

                    January, 2000                 17

There is complete vacuum in terms of DL
solution in the country
This is an opportunity for us
Need to keep a watch on institutions with
–   Strong IT infrastructure/plans
–   Fully automated library
–   IT aware librarians
–   Institutional and library web sites
–   Libraries offering services over intranets

Thank You!
