| Research Abstract |
RFID technology is a core IT technology in the coming ubiquitous computing era. It has great features such as contactless communication, big memory, battery-less and so on. It will be used many services that have been provided with magnetic cards and barcordes. The library is a promising application field for the technology, since the library work, especially dealing with materials, is time- and labor-consuming. Reduction of time for inventory and number of counters will be a great benefit for libraries. The goal of this research is to investigate the effect of the RFID system to middle and large libraries.
The trend survey of RFID tag systems is an important object of this research. We have visited domestic and foreign libraries and RFID related makers to exchange of information and opinions. We have also visited RFID related exhibitions, such as AUTO-ID Expo.
We have installed a RFID tag system to the Chikushi branch library of Kyushu University Library, and investigated the effect of

the ID tags to library jobs. We started by attaching 13.56MHz tags to about 5,000 books, and then additional 20 thousand ID tags have attached. As the results we know that self-checkout machines and book detection systems are practically useful with operational procedures, and that checking books with a handy RFID reader reduce drastically checking time compared to time with a barcorde scanner. We have also recognized some problems. For example, real-time inventory is impossible using intelligent bookshelfs, because existing RFID readers are not enough to detect many RFID tags in many orientations simultaneously.
So we have investigated the applicability of intelligent bookshelfs with new, highly accurate RFID readers to new library services with the help of some RFID reader maker. Our experiments show that the intelligent bookshelf are accurate enough to detect all RFID tags attached to books within the bookshelf, even if some books are inclined or laid horizontally. Moreover, we can find absence of a book right away when it is taken from the bookshelf, since the readers detect only tags within the bookshelf. When we attach tags to thin periodicals with around 6mm thick, the accuracy is quite low. However, the accuracy is increasing drastically, when we attach tags on two different positions of the periodicals alternately. Such intelligent bookshelves will enable library to provide new library services, such as OPAC with more precise book positions, although currently the RFID system is introduced into many libraries for the sake of laborsaving.
