However, in recent years, the value of genealogical resources has been ignored or mis-estimated by the public. The number of related research papers is small, and the practice of augmented reality (AR) application in public libraries rarely involves the public service of genealogy. The published papers and practice of knowledge service of genealogical resources are the cornerstone of this research work. The purpose of this study is to give dynamic cultural value to genealogy resources in public view by exploring the innovative mode of genealogy resources in libraries. [Method/Process] This study investigates relevant domestic literature and work practices, as well as the practice of domestic and foreign libraries using AR to carry out public knowledge services. This research is based on the characteristic genealogy literature resources of Shanghai Library, and the work is based on the digital humanities construction such as Chinese genealogy knowledge service platform, including the construction of "Chinese genealogy knowledge service platform", and the mining and sorting of genealogy information, and the construction of "human name standard database". The theoretical source of this study is that genealogy and surname culture construct each other's value, and they show the value of genealogy resources from the perspective of surname culture. Finally, this study completed the practice innovation of public knowledge service based on genealogy resources in the East Library of Shanghai Library. [Results/Conclusions] Through the practice of "AR surname wall", Shanghai Library, according to our own characteristics of knowledge popularization, provided diversified knowledge services, technology and art integration and obtained the beneficial experience. We found that the existing service is too dependent on technology and artistic effect, did not solve the problem of readers superficial reading, and there is a lack of knowledge service. Based on the practice of public knowledge service of genealogy resources and digital technology, Shanghai Library provides insights into giving cultural value to genealogy resources, has made an innovative attempt in public knowledge service, and made progress and development of the popularization of genealogy knowledge and genealogy culture. In the process of practice, a lot of useful experiences have been obtained, and some problems are still yet to be solved, which not only makes more people realize the cultural value of genealogy resources, but also helps us understand the development of library resources boosted by digital humanistic technology, and the breakthrough of some exhibition items of the East Library of Shanghai Library on traditional exhibitions.
