This article employs a qualitative research approach using a literature review method to examine the transformation of technological innovation in libraries, particularly the shift from traditional catalog systems to the adoption of artificial intelligence (AI). Research data were obtained through a critical review and analysis of various relevant scholarly sources, including academic journal articles, books, and other publications discussing the application of AI technology in the library field. The analysis was conducted by identifying patterns, concepts, and emerging issues related to AI implementation, encompassing its benefits, challenges, and impacts on service efficiency and user experience. The findings indicate that the utilization of AI has the potential to enhance the quality of library services, although it still faces obstacles such as the readiness of human resources, implementation costs, and data security concerns. Therefore, AI-based technological innovation needs to be strategically integrated to ensure that libraries remain relevant in meeting information needs in the digital era. The conclusion of this article emphasizes that the adoption of innovative technologies, particularly AI, is a crucial step for libraries to remain relevant and effective in serving the information needs of society in the future.
