novel search and retrieval techniques such as federated search using data fusion [1], mediator
architecture [2] and integrating links and ranking;
audio-visual and multimedia information retrieval systems;

collaborative, visual, 2D and 3D interfaces.
(i) Digital content and collections: This category refers to individual digital objects and to
collections of objects in repositories encompassing a variety of materials in different digital
formats. One major challenge with regard to metadata is the diversity of digital informa-
tion formats. In this category there are challenges associated with digital content: for
instance conversion of printed materials into digital format and the creation of digital-only
materials for the purpose of a particular digital library. In addition, a host of other issues
related to digital content and collections have been discussed.
These include: collection development strategies, policies and management;
identifying collections of information which are not accessible or usable because of
technical barriers;
formulating strategies for sustainable and scalable collections;
encouraging the development of new collections;
the creation of digital objects and electronic publishing;
the creation of new genres of digital objects; and
issues related to digital preservation and Web archiving.
(ii) Interoperability: Interoperability is one of the most heavily discussed issues in digital
library research. The requirement for interoperability derives from the fact that various
digital libraries with different architectures, metadata formats and underlying technologies
wish to effectively interact, something they can do through applying a range of common
protocols and standards.

Notes The Open Archives Initiative (OAI) protocol (OAI, 2002) is the most widely discussed
and investigated standard for cross-repository interoperability.
It allows distributed digital libraries to expose their metadata to a wider range of search and
retrieval services and also to extract metadata from Web databases. Z39.50 has also been mentioned
as another interoperability protocol for online catalogues and other types of information retrieval
systems on the Web.

5.2 Role of Computers
(a) Minimum Preparation for Work
Associates degree in computer science or;
Graduation from high school or equivalent; and two years experience using computer
software applications preferably in a public library.
(b) Nature of Work
This is professional work, instructing library staff and the public in the use of computer
applications software.
An employee in this class promotes the use of public library computer facilities and
services. The work involves creating and implementing programs teaching the use
of computers to individuals and groups. An employee in this class receives supervision
from the Department Director or designee.
