Digital libraries store collections of digital objects like text, images, audio, and video that can be accessed remotely via computer networks. They organize and provide search capabilities for these collections. Digital libraries come in different types, including document digital libraries for electronic publishing and data warehouses for combining data from various sources. While digital libraries provide advantages like increased access and preservation, they also involve high costs for digitization, technical expertise, and network infrastructure.

3. INTRODUCTION
• A Digital Library is a special library
with a focused collection of digital
objects that can include text, visual
material, audio material, video
material, stored as electronic media
formats, along with means for
organizing, storing, and retrieving the
files and media contained in the
library collection.
• The electronic content may be stored
locally, or accessed remotely via
computer net works. An electronic
library is a type of information
retrieval system

4. • A digital library is a library in which
collections are stored in digital formats
(as opposed to print, or other media)
and accessible by computers. The
digital content may be stored locally, or
accessed remotely via computer
networks. A digital library is a type of
information retrieval system.
• It provides the architecture to model,
map, integrate, condense and
transform scattered information housed
in digital documents. Companies can
perform more substantive, accurate
and consistent analyses using the
digital library as a foundation for
decision support system.

5. TYPES OF DIGITAL LIBRARY
DOCUMENT DIGITAL LIBRARIES
• It is a distributed network of
interlinked information mainly
for electronic publishing.
• Books, reports, paper
materials, electronic files,
video and audio.
• Digital document formats( word
processing, spreadsheets,
audio recordings, digital video)
DATA WAREHOUSE
• These are Central Information
repositories for combining and
storing vast amounts of
historical and reference data
from a number of different
sources.
• It is a physical separation of
an organization’s operational
data systems from its decision
support systems.

6. SOFTWARE
6
• There are a number of software packages for use in general digital
libraries, for notable ones see Digital library software.
• Institutional repository software, which focuses primarily on ingest,
preservation and access of locally produced documents, particularly
locally produced academic outputs, can be found in Institutional
repository software.
• This software may be proprietary, as is the case with the Library of
any authorized company which uses DigiBoard and CTS to manage
digital content.

7. • No physical boundary
• Round the clock availability
• Multiple accesses
• Structured approach
• Information retrieval
• Preservation and conservation
• Space
• Networking

8. 8Jens Martensson
• Although digital libraries do
away with these fees, digital
libraries can be no less
expensive in their own way to
operate.
• Large costs incurred for the
conversion of print materials
into digital format, for the
technical skills of staff to
maintain them, and for the
costs of maintaining online
access (i.e. servers, bandwidth
costs, etc.).
