The emergence and application of metaverse technologies across various industries are driving libraries towards the development of spatial intelligence from intelligent spaces. The practical experience gained from the construction of virtual libraries on platforms like "Second Life" has contributed to the advancement of spatially intelligent libraries in the metaverse era. In this era, library professionals need to embrace a new understanding of the potential provided by the metaverse for library development, guided by technology-driven concepts.  The library should uphold the principles of symbiosis and integration between virtual and physical library spaces, striving to promote the cultural, educational, and occupational development of metaverse libraries.
