<p>Digital libraries are undergoing a profound transformation driven by advances in user experience (UX) design, artificial intelligence, and interactive technologies. No longer conceived solely as repositories for information retrieval, contemporary digital libraries increasingly support exploratory search, learning, collaboration, and sensemaking across diverse user populations. This special issue brings together research that examines next-generation user experiences in digital libraries, with a focus on novel interface paradigms, emerging interaction modalities, and inclusive, user-centred design methodologies. Collectively, the contributions highlight how UX innovation can enhance usability, accessibility, engagement, and learning, while also addressing the evolving expectations of scholars, students, and the wider public. The issue provides both conceptual frameworks and empirical evidence to guide researchers and practitioners in designing digital library systems that are adaptive, reflective, and responsive to human needs.</p>
