Artificial Intelligence (AI) is the area of computer science focusing on creating machines that can engage in behaviour that humans consider intelligent. These intelligent developments rely on deep learning, machine learning and natural language processing that help computers accomplish specific tasks by processing large amounts of training data to help the system recognize patterns, input data to drive predictions and feedback data for improving accuracy over time. Given that computers and internet deeply affect the library and information service field, asking a machine for answer is quickly becoming a normal everyday activity. Nigerian libraries are also working with machine learning technologies, to enhance classification schemes, indexing, information retrieval, reference and improve search and recall precision. This paper is an effort to identify possible ways libraries in Nigeria can build expertise and enhance the moral principles that govern the actions of these artificially intelligent machines to ensure that they behave in a way that would fit the ethical framework for librarians and explore the various possible applications of artificial intelligence in their operations
