This study is one of the first studies that dealt with smart library management systems and the measurement the library smart index (LSI). The study aims to identify the reality of smart library management systems in the American University Library and how to plan for them. And studying smart library management systems based on RFID technology, and he presented the emerging technology in the sample libraries of the study, in addition to measuring the university library smart index. (LSI) scale was used, and to identify the challenges and obstacles facing the American University Library staff after the application of RFID technology, the study relied on the case study approach as a main approach. To collect information about smart library management systems through observation and personal interview with library staff, The study reached several results, the most important of which is the self-check out service comes in the first rank with 72.1% as the smart library system based on RFID technology, then RFID applications in book management in the second rank with 63.3%. The results of the study confirm that libraries are one of the smartest using the emerging technologies available at the university library The study recommends the need to pay attention to standards for measuring intelligence in libraries and smart library systems through research and studies on these systems, which helps to spread awareness and apply them in Egyptian libraries.
