Abstract : Radio Frequency Identification (RFID) is a new generation of Auto Identification and Data collection technology which helps to automate business processes and allows identification of large number of tagged objects like books, using radio waves. RFID based Library Management system (LMS) would allow fast transaction flow for the library and will prove immediate and long term benefits to library in traceability and security. The proposed system is based on UHF RFID readers, supported with antennas at gate and transaction sections, and library cards containing RFID-transponders which are able to electronically store information that can be read / written even without the physical contact with the help of radio medium. This paper presents the experiments conducted to set up RFID based LMS. 1. INTRODUCTION RFID technology is being implemented in a number of industries. Supply chain implementation is perhaps one of the most frequently mentioned applications of RFID tags and equipment. Retailers such as “Wal-Mart” and grocery stores such as “Albertson’s” have begun to make it mandatory for their suppliers to tag merchandise destined for their stores. There is, however, a key difference to the library’s inventory as compared to that of a warehouse or a retail outlet. In the warehouse and retail supply chain, goods come in and leave. Only occasionally are they returned. The retail sector is looking at RFID as a "throwaway" technology that hands an item to a customer which gets discarded. Yet the item wise unit cost of including an RFID tag is much more than the cost of printing a barcode on a package. In libraries, items are taken out and returned many times. Thus the same RFID tag is re-used many times.  The libraries across the globe started to use RFID to speed up the self check in/out processes, to control the theft and to ease the inventory control in library. The barcode technology is slowly getting replaced by the RFID technology. The RFID tag does not have to be visible for detection. It can be read even when it is embedded in an item, such as in the cardboard cover of a book or in the packaging of a product. It can also store data such as stack number, accession number, book number, author information etc., but barcode is limited to just an identification number. The paper presents the study taken and corresponding experiments conducted for integrating RFID to existing LMS of CDAC. The remaining sections of this paper are organized as follows: Section II describes about Library, the tasks involved in that, problems faced by librarians and RFID’s role in automating some of the tasks of library, Section III describes about the technical specification of the hardware and tags used in project (RFID based LMS), Section IV describes about the modules developed in project, Section V describes about the experiments conducted to find out the proper tag position in book and Section VI describes about the benefits of the project. 2. RFID in Library A library is a collection of information, sources, resources, books, and services, and the structure in which it is housed. Apart from books many libraries are now also repositories Proceedings of ASCNT – 2009, CDAC, Noida, India, pp. 227 – 234

and access points for maps, prints, or other documents on various storage media such as microform (microfilm/microfiche), audio tapes, CDs, LPs, cassettes, videotapes, and DVDs. Libraries have materials arranged in a specified order according to a library classification system, so that items may be located quickly and collections may be browsed efficiently. Reference stacks are different which has only reference books and only selected members.  CDAC Library is a large one having 17,000 books and staffed by both paraprofessionals and professional librarians. The following are...
