The document discusses the concept of Library 2.0, which refers to modernized library services that apply the interactive and collaborative principles of Web 2.0. It involves applying technologies like blogs, wikis, and social networking to allow users to participate in the creation and sharing of information resources. The document outlines various Web 2.0 tools and techniques that can be adopted by libraries, such as RSS feeds, tagging, social bookmarking and mashups. It argues that implementing these tools will change libraries by making their collections more interactive and accessible while focusing services on facilitating information transfer.
