Abstract: In the face of the problems such as poor interlibrary interconnection, failure to get through the core business data, unbalanced resource construction and utilization, and lack of unified technical standards and norms in the establishment of the public library community, “Digital intelligence” will connect the five elements of the public library community, including the concept, mechanism, readers, resources and technology, and will comprehensively and systematically reshape the institutional mechanism, organizational structure and process means by way of digital technology, thinking and cognition. Zhejiang Public Library seized the opportunity of digital reform, planned the system design with digital thinking, and promoted the service upgrading of public library with digital technology. It built and opened the first document information resources co-construction and sharing platform in China, and achieved remarkable results. In view of the problems of the digital-intelligence-enabled public library community, such as incomplete data sharing, difficult platform expansion, lack of standard system, and derivative legal risks, we need to explore and develop from the aspects of chain revolution, top-level design, system remodeling, system engineering and so on in the future.
