The advent of Artificial Intelligence (AI) has ushered in a new era in library science, offering unprecedented opportunities to enhance information management, user experiences, and the overall efficiency of library operations. This paper explores the multifaceted applications of AI in the field of library science, emphasizing its potential to revolutionize traditional practices and adapt to the evolving needs of the digital age. We delve into various aspects of AI integration in libraries, ranging from information retrieval and search optimization using natural language processing algorithms to the development of AI-driven recommender systems that tailor resource suggestions to individual user preferences. AI's role in cataloging and metadata creation is highlighted, showcasing how machine learning can expedite the cataloging process while ensuring accurate and consistent metadata. Additionally, the paper discusses AI's contributions to preservation and conservation efforts, as well as its assistance in collection management through predictive analytics.
