Abstract: With the deep integration of technologies such as artificial intelligence (AI), the Internet of Things (IoT), and big data, university smart libraries are transitioning from traditional "book repositories" to "integrated knowledge service hubs". In this transformation, balancing reader demands with library resource management through technological approaches has become a core issue for sustainable development. This paper examines technological application scenarios in smart libraries and explores how intelligent services optimize resource allocation, enhance user experience, and ultimately achieve efficient synergy between user needs and library operations.
