As the main force of the socialist public cultural service system, the library plays an irreplaceable role in the improvement of national cultural soft power. With the rapid development of society and economy, our country’s urbanization has increased unprecedentedly, while various urban problems have gradually emerged. In order to solve the problems of traditional library preservation and operation, this paper proposes a new model of library development based on the era of "smart +". Through case investigation, a case template is constructed, and an evaluation matrix is created using comprehensive quantitative and qualitative analysis. , Use models to verify various influencing factors, and use reliable data to support the scientific nature of the conclusions. The extension of the knowledge service of smart libraries needs to be optimized and upgraded respectively. Experiments have proved that compared with traditional books, libraries in the "smart+" era have great advantages. In the operation of libraries, the operating efficiency of smart libraries is about 40% higher than that of traditional libraries. Personnel etc. are better than traditional library management. This shows that with the development of technology, smart libraries have increasingly become the development trend of library management.
