This report, authored by Paul Anderson and peer-reviewed by Mark Hepworth, explores the concept of Web 2.0 and its implications for education, particularly in the context of library collection and preservation activities. The report argues that Web 2.0 is more than just a set of new technologies and services; it is underpinned by six powerful ideas that are transforming how people interact. These ideas include collaboration, contribution, and community, which are reflections of the network's power and the effects it produces at both micro and macro levels. The report distinguishes between Web technologies (ongoing development by the W3C) and recent applications and services (social software), and examines the manifestations and adoption of these services. It highlights the importance of understanding the interplay between these strands to grasp the strategic implications of Web 2.0. The report also discusses the impact of Web 2.0 on libraries, particularly in terms of content quality, user-centered change, and the challenges of collecting and preserving Web 2.0 content. Finally, it looks ahead to the potential impact of future technologies, such as Web 3.0.This report, authored by Paul Anderson and peer-reviewed by Mark Hepworth, explores the concept of Web 2.0 and its implications for education, particularly in the context of library collection and preservation activities.
