The evolution of the internet from Web 1.0 to Web 3.0 has significantly influenced how libraries function, communicate, and deliver services. Web 2.0 technologies introduced interactivity, user participation, and social collaboration, while Web 3.0—driven by artificial intelligence, blockchain, and semantic web technologies—ushers in personalization, data security, and intelligent information management. This paper examines how these advancements are transforming library services, from digital reference and cataloging to community engagement and data-driven decision-making. Through a qualitative review of literature and case examples, the study highlights the growing role of Web 2.0 and Web 3.0 in enhancing library accessibility, efficiency, and user experience in the digital era.
