Synopsis Reference services are public services created by libraries seeking to expand their services and to help readers with varied needs. Traditionally libraries are maintaining a reference desk or information desk, where professional librarians offer help to library users. Unlike traditional reference services, digital reference services allow patrons to submit questions and receive answers via the Internet and other electronic means. The users get connected with librarians or information professionals and receive direct assistance wherever and whenever they need it. The book aims to give the reader a thorough overview and a broader understanding of the possibilities of reference services. It introduces the reader to the sophisticated, imaginative and interesting aspects of the complete reference process. It also provides an authentic description of the ongoing and important changes and developments in information technologies and particularly the role of the internet in the reference process. The material covered in this book will be immensely useful to students, general library users, teachers and library professionals alike.
