This paper describes the use of Radio Frequency Identification (RFID) and Wireless Sensor Networks (WSN) to automate the process of finding, borrowing and returning books at the library. This would be an advance over scanning barcodes, which still require a lot of human intervention. The obvious analogy here is with the no-checkout store unveiled by Amazon earlier this year. The paper described the algorithms in detail and describes a test of the system. My only criticism is to question why we still need to borrow physical books. But of course the same approach can work with any educational resource.
