Libraries for centuries have played important role in supporting research in all subjects and disciplines within their host universities and colleges. But the last decade has brought a sea change in relationships between researchers and libraries. Information and communication technology (ICT) enabled products and services, and the availability of online information resources have changed the way the services academic institutions and libraries now provide to their researchers. This book will be useful for the students of library and information science, working librarians and information professionals and research scholars. The book also covers legal and ethical considerations with the use of information and communication technologies in the Chapter 2. It also provides survey findings of the use of ICT enabled Library services by library users at National Physical laboratory; New Delhi-India. The authors hope that this book will be well placed on the shelves of the many libraries over the world.
