[Purpose/significance] The application of generative artificial intelligence in smart library services has great potential and advantages, which can provide more efficient and intelligent services for smart library. However, since the legal status and responsibility of AIGC is not clear, the ensuing legal problems cannot be ignored. [Method/ process] This paper reviews the concepts of generative artificial intelligence and artificial intelligence-generated con⁃ tent. Then, it analyzes the main application scenarios of generative AI in smart library, including virtual consulting ser⁃ vice, subject knowledge service, micro, small and medium-sized enterprises thematic push service, reading promotion service and information literacy education and training service. Finally, it discusses the liability issues arising from AIGC accuracy, user privacy, copyright ownership and invalidation of relevant rules and algorithmic discrimination of AIGC in the main service scenario of intelligent library, and puts forward countermeasures. [Result/conclusion] The in-depth analysis of the internal logic behind these legal problems and the search for systematic solutions from the lev⁃ el of legal theory need to be further explored in the follow-up research.
