This paper presents a literature on the impact of Artificial Intelligence (AI) in English language teaching and library practice and its impact on library operations. This study aims to provide researchers with a comprehensive understanding of AI in the English language teaching and library context. This paper aims at analyzing an artificial intelligence platform that can be used in examining lecturers’ proficiency levels in English teaching and library practice in Nigerian universities. It draws attention to how AI facilitates personalized learning experiences by adapting to individual teachers’ teaching style, pace, and proficiency levels. The paper examines the proficiency levels of lecturers in Nigerian universities regarding the utilization of AI features in three innovative presentation software tools: MS PowerPoint, Canva, and Gamma. Through the application of AI playing as a pivotal tool in enhancing research, teaching and learning experiences, the study explores the significance of PowerPoint literacy in modern English teaching and learning settings. The method of research design is descriptive. The population of the study consists of the entire academic staff in Nigerian universities. The sample size used is made up of 600 lecturers. Data are analyzed using descriptive statistics of mean, standard deviation on a 4-point Likert Scale. The findings of this study serve as a base for developing training programs and interventions to enhance PowerPoint literacy skills in the teaching of English Language and library practice in Nigerian universities. The findings also illustrate that Artificial Intelligence technology is useful for developing teaching of English Language and library practice. The major limitation of this study is that it does not examine the extent of AI role in teachers’ teaching and students’ English learning. The information presented in this paper serves as a valuable resource for researchers interested in exploring the use of AI in English language teaching and library practice.
