RFID-based integrated library management system (ILMS) based on open-source KOHA is implemented at IGCAR Library. Latest RFID devices (figure-3) such as electronic article surveillance gates, hand-held readers, programming stations, and new generation tags are commissioned for smooth library operations. The article surveillance gate was integrated to the ILMS and programmed to display the unauthorized checkouts in addition to an audio alarm. The Library membership cards were integrated to employee cards of various Units of DAE at Kalpakkam. The Library entry is protected by RFID, which allows all Personnel from any DAE unit visiting IGCAR. The centralized Library Gateway Portal (LGP) of SIRD (Figure-2) is an access point to all the subscribed and in-house information resources and services.
