The purpose of the study was examined librarians’ awareness, perception and acceptance of artificial intelligence and utilization in library service. To achieve this objective, three research questions and three hypotheses were stated. Empirical and theoretical literature were reviewed conceptually, theoretically, and empirically. A cross sectional research design was used to collect information from 342 librarians in the libraries in the study area. A questionnaire title: Librarian Perception, Awareness and Acceptance and Utilization of Artificial Intelligence (LPAAUAIQ) was used for data collection. and the data collected were analysed using simple regression and the result presented appropriate. The study demonstrated that perception, awareness, and acceptance significantly contribute to the utilization of AI in libraries. Positive perceptions of AI's usefulness, heightened awareness of its capabilities, and acceptance of AI as a valuable tool are crucial factors that drive its adoption and integration into library services. These findings are consistent with the Technology Acceptance Model (TAM), which highlights perceived usefulness and ease of use as critical determinants of technology acceptance. Implications for the study were discussed.
