Information Technology in Library and Information Services »

"Information technology (II) is the boon of the present century. It gives accessibility to information at the finger tips. The technological developments in information transfer emphasize the fact that universal availability of information is no more an utopian concept. The promising and diversified possibilities of information technology have reduced the space and time between people, country, continent and ultimately have led to the emerging concept 'global society' and 'global village'." "The prospects of application of information technology in library and Information Services are many fold and in today's time of rapid development in the field of science and technology, we can not remain untouched by it." In this context the entire work related to various technologies is divided into fifteen chapters. An attempt has been made to identify the impact of electronic media in modern libraries and information centres in the context of the information age in the 21st century.
