During recent years library science has become a vast and specialized field of study using a technical terminology. With the above point in view, this book has been especially written to meet the requirements of semi-professionals undergoing short-term training. This will serve as an introductory work for students preparing for their library science/information science/documentation diplomas and degrees. Librarians working for small libraries will also benefit equally from it.
