In the digital era, with the increasing popularity of smartphones and the rapid evolution of mobile technologies, the way libraries provide and access information is undergoing significant transformation. Academic libraries are extending their services beyond physical spaces by adopting mobile platforms, social media tools, and dedicated mobile applications to enhance student engagement and promote a culture of reading. The integration of library mobile applications and Mobile Online Public Access Catalogues (M-OPACs) has enabled users to conveniently search, reserve, and access resources through their handheld devices. This study explores the role of mobile technologies in academic libraries with specific focus on library mobile applications and M-OPAC. It examines their features, benefits, and challenges, and highlights how these tools contribute to creating seamless, user-friendly library experiences. The paper also discusses implementation challenges such as usability, platform compatibility, and data security while emphasising their potential to transform academic libraries into flexible, accessible, and digitally inclusive spaces.
