Abstract: 【Purpose/significance】Metaverse is a super-large virtual space that is scalable, interactive, and network rendering. In the initial exploration stage of the Metaverse Library, the development of the "Second Life Library" was limited due to the lack of realism and immersion. It was necessary to discuss the reform of the library from the perspective of immersion theory to promote the develop⁃ment of Metaverse in the library field. Explore and apply.【Method/process】Analyze the equipment, technology and functions of the Metaverse Library from the perspective of immersion theory, construct the framework model of the Metaverse Library, and explore the reconstruction of the attributes and relationships of the“people, fields, and objects”of the Metaverse Library. Discuss the development strategy of Metaverse Library.【Result/conclusion】The relationship between "human" and "fields and objects" in Metaverse has
changed from one-way service acceptance to a two-way interactive relationship between receiving service and active participation in creation, and enhance user participation in Metaverse through the purpose of behavior. The immersion of the library.【Innovation/limi⁃tation】Reconstruct the attributes and relationships of the "people, fields, and objects" of the Metaverse Library, enrich the functions of the Metaverse Library, and enhance the immersion of users' participation. However, since Metaverse is still in its infancy, the emer⁃gence of disruptive new technologies in the future will change the basic structure of the Metaverse Library.
