【Purpose/significance】At present, in the application of smart library, the high-precision positioning of electronic books can⁃

not be realized, which leads to the poor overall service quality and unsatisfactory use effect of smart library. Therefore, in the context of 5G information management, this research aims to provide readers with more accurate and convenient services by constructing a smart library VR service platform.【Method/process】This article considers the framework composition, hardware selection and functional module design of the smart library service platform, and constructs a smart library VR service platform by integrating VR technology.Based on a prototype example of a university library, simulation tests and comparative analysis of the functions and performance of the designed platform are carried out.【Result/conclusion】The experimental results show that the functions of the designed platform meet the needs, the positioning is more accurate, the time-consuming level is ideal, and it can provide higher quality services for smart li⁃brary users.【Innovation/limitation】However, since this research only tested the book positioning and retrieval functions of the plat⁃form, the test content was not comprehensive enough, so further improvement is needed in subsequent research.
