Abstract: Exploring the path of deep integration between AI and library services is one of the effective measures for libraries to break the barriers of development in the era of "Internet +", and provide practical cases for library's innovation, development, transformation and upgrading. Based on a brief introduction of the challenges AI posed to library service in the aspects of resource construction, information organization and information service, this paper probed into the innovative ways of deep integration of AI and library services from the aspects of literature resource, human resource, shared space and service items, and emphasized the importance of thinking mode and decision-making structure transformation in "AI+library" service.
