4. Introduction
Digital libraries encompass a whole range of information services related work such as
Organization of digital information
Information retrieval
User interface
Archiving and preservation
Services and social issues
Evaluation and applications to particular areas

5. Features of Digital Library
Low cost, including all hardware and software components
Technically simple to install and manage
Robust
Scalable
Open and inter-operable
Modular
User Friendly
Multi-user (including both searching and maintenance)
Multimedia digital object enabled
Platform independent (including both client and server components) interoperable

6. Why DSpace Digital Library
DSpace is
An open source technology platform which can be customized and its capabilities can be extended
A service model for open access and/or digital archiving for perpetual access
A platform to build an Institutional Repository and the collections are searchable and retrievable by/on the Web
To make available institution-based scholarly material in digital formats. The collection will be open and interoperable.

7. Architecture and System Requirement
The DSpace system is organized into three layers
The Storage Layer: responsible for physical storage of metadata and content
The Business Layer: deals with managing the content of the archive, users of the archive (e-people), authorization, and workflow
The Application Layer: containing components that communicate with the networked world outside of the individual DSpace installation

8. DSpace is a joint project of MIT Libraries and Hewlett-Packard Labs
