Amy Benson discusses how libraries are evolving to Library 2.0 models to better serve patrons in a Web 2.0 world. Key aspects of this evolution include embracing user participation through user-generated content and social software, providing personalized and mobile services, and integrating library data with external resources through mashups and semantic approaches. Benson urges libraries to explore new technologies, embrace change, and focus on serving patrons through an ethos of collaboration, community, and open information sharing.
