Several Wisconsin libraries are moving to radio-frequency identification (RFID) of materials as a way of cutting staff time needed for handling books, CDs, DVDs and other materials. Returned materials can automatically be sorted into the proper receptacles for return to other libraries or reshelving in the proper area of the library. The systems are expensive but provide efficiencies, reducing staff hours needed for routine tasks and enabling staff to spend more time serving patrons directly. A July 19 Milwaukee Journal-Sentinel article describes the experience of New Berlin, West Allis, and Greenfield, among others, who have RFID or are exploring their options.
