Library Science is a modern discipline. Earlier regarded as storehouses for preservation of manuscripts and books for reading and reference purposes, publicly or privately, the functions of the library today have assumed multifold dimensions today. Library management is such a vast field that it is not possible within the compass of a single volume to cover the whole of it comprehensively. Hence the need of this series. The present book is intended to serve as an introduction to the subject. The application of information technology in libraries results in increased operational efficiency. IT increases the productivity of library staff. It relieves professional staff from mundane jobs that involve a lot of duplication so that they can be fruitfully used for user oriented library services. It improves the quality of services rendered by the library. Use of information technology ensures ease of functioning, accuracy and economy in human labour with greater speed. The exponential growth of information has made manual systems redundant giving way to computerised information storage and retrieval tools. In this book, the fundamentals of library science like definition, purpose, social concept, types, public, spend, academic have been introduced. Various policies and procedures related to library science are also appended to make it comprehensive in a holistic manner.
