Abstract: The urban reading service system is a comprehensive service system that includes radio and television stations, new media platforms, newspapers, magazines, publishing houses, bookstores, schools, and libraries (rooms) to promote reading for all. “Library City” is a library reading service system and digital service network that cover the whole city geographically and spatially. Through the scientific layout of library service outlets, it integrates the city’s literature information and characteristic resources, and realizes the co-construction of the city’s literature resources. The convenience and zero threshold of sharing and library literature information services are an important part of the construction of a city’s reading service system and an important symbol for the in-depth promotion of reading for all. In this paper, by explaining the construction background, concept, plan design, implementation process and effectiveness of the “Cangzhou Model” of the “library city”, this paper proposes an innovative construction path for the urban reading service system for discussion by colleagues in the library community.
