In an era marked by rapid technological advancements and an explosion of information, libraries face the daunting challenge of adapting to their patrons’ changing needs and expectations (Harisanty et al., 2022; Huang, 2022; Panda & Chakravarty, 2022; Yoon et al., 2021). This global problem is twofold: on the one hand, libraries must contend with the deluge of digital resources and the complexities of information retrieval in an increasingly digitised world (Feng et al., 2005; Fombad et al., 2023; Frederick, 2023; Moonasar & Ngoepe, 2023). On the other hand, they are tasked with enhancing user experiences and maintaining relevance in the face of evolving user preferences and behaviours. In this context, the integration of artificial intelligence emerges as a promising solution, offering libraries the tools to streamline operations, personalise services, and optimise resource management (Borgohain et al., 2022; Harisanty et al., 2023; Hussain, 2023; Wang et al., 2023).
Several contributing factors underscore the significance of studying AI’s impact on libraries (Aithal & Aithal, 2023; M. Y. Ali et al., 2022; Cox, 2023; Lund & Wang, 2023). Firstly, the exponential growth of digital information presents libraries with unprecedented challenges in effectively curating, organising, and disseminating knowledge. Traditional methods of information retrieval and management are needed to meet the diverse needs of users in today’s information ecosystem (N. Ali et al., 2023; Casselden, 2023; Catarci & Kimani, 2013; Nugroho et al., 2023; Sinha, 2023). Secondly, users’ rising expectations for seamless and personalised experiences necessitate innovative approaches to library services. AI-powered solutions, such as intelligent recommendation systems and chatbots, offer avenues for libraries to deliver tailored experiences and enhance user engagement (Adetayo, 2023b; Barsha & Munshi, 2023; Hodonu-Wusu, 2024; Lo, 2023; Michalak, 2024). Thirdly, the emergence of AI technologies has sparked a surge of research and development across various domains, including library science(Fernandez, 2023; Subaveerapandiyan et al., 2023; Zhang Zhixiong, 2023). Understanding the research landscape through bibliometric analysis enables scholars and practitioners to identify key trends, influential actors and potential collaboration areas, thereby fostering AI advancement in library settings (M. Y. Ali et al., 2020; Ding, 2010; Sharma et al., 2023; Talafidaryani et al., 2023).
In light of these contributing factors, this research seeks to investigate the multifaceted implications of AI in libraries through a comprehensive bibliometric analysis. This study aims to provide valuable insights into AI research’s current state and future directions in library science by examining publication trends, identifying research themes and mapping collaboration networks.
