Synopsis Technology is changing the nature of libraries and librarians, and it continues to exert a major influence on the strategic direction of libraries in society. Today, the library services are transitioning from local traditional collection to global resources provided on demand via the most advanced networking technologies. It is now possible to retrieve information independently of time zones and geographical location, and to obtain the most uptodate information from the form of the library without walls, or the virtual library. Libraries of all types are challenged to provide greater information access and improved levels of service, while coping with the pace of technological change and ever-increasing budget pressure. As a result professional librarians must be computer literate and knowledgeable about internet technologies to fully participate in the planning design, and implementation of future library services. This book indents to describe information technology advances that have enhanced the ability of libraries to serve their communities, lower their costs, and fully participate in the new networked world. It enables the readers to understand the process of electronic dissemination of information, the impact of the internet on libraries, the changing responsibilities of library professionals, the new paradigm for evaluating information, and characteristics and functions of today’s library personnel. It will be highly beneficial for practising librarians and students in library science and the social sciences.
