To achieve transformation, libraries must undertake a profound and rapid reconfiguration of space. The spatial literacy competencies of librarians are directly related to the construction and service level of library spaces. This paper clarifies the concept of spatial literacy and its constituent elements. Using the method of systematic literature review, the current status of research on librarians’ spatial literacy is analyzed from three aspects: spatial theory, spatial method, and spatial practice by focusing on the trajectory of library space-related literature.
