Library is a place where book are kept for reading, study or reference. The main function of the Library is to collect, preserve and disseminate knowledge to the society. In the early periods the libraries were considered as the store house of books where books were kept in closed access system under key and lock. The Librarian was thought to be the custodian of these books. In the presented scenario, the situation has been totally changed. The libraries are observing open access system in which users is free to use any of library material. The role of the Librarian is considered as a manager/disseminator of knowledge. Libraries are fully automated. Electronic material is replacing the print material gradually. Softwares are used for housekeeping operations. RFID and bar code technology is proved to be boon for users and staff as well.
