Abstract
The purpose of this study is to investigate and analyze the architectural space of public libraries based on the concept defined in the changes in library policies and social paradigms. Through the literature survey, active information search and autonomous visit and stay are recognized as basic characteristics of the public library. Based on the previous finding, the study analyzed the area ratio, spatial configuration, and topological characteristics of 40 public libraries in South Korea, and the results are as follows. There is confirmed that the space ratio of the Public-use part and the Data-use part is higher than that of the public libraries of the previous generation, and the 'reading deck' and 'stairs in data use sector' are found as a new planning elements of the public library planning. In the integration value of individual spaces using spatial syntax, the public library with these elements is shown to be formed with the topological center of the whole building centered on the reading deck and the data use space.
