Information and 
			Communication Technology has revolutionized the concept of 
			libraries. Each and every library is slowly getting digitized. A 
			'e-library' comprises digital collections, services and 
			infrastructure to support lifelong learning, research, scholarly 
			communication as well as preservation and conservation of our 
			recorded knowledge. It is also a process of democratization of 
			information. This article will discuss the factors that will 
			necessitate the traditional libraries to get digitized, as well as 
			the definition, advantages and disadvantages of digital libraries, 
			the requirement for building a digital library etc.
				
We are in the age of a networked society where information 
			technology in addition to its use in all spheres of human activity 
			has been used extensively to record, store, and disseminate the 
			information in the digital form. Information technology has almost 
			converted the world into a global village. The revolution in the 
			information technology sector is influencing medical information. 
			Libraries are also changing to meet the demand put on them. The new 
			generation whose demand for information is never met is always 
			demanding that traditional libraries should be developed as a well 
			equipped and interconnected as e-libraries.
