The document summarizes a presentation about the LASSIE project which explored how libraries are using social software and web 2.0 technologies. The project conducted a literature review and case studies on the use of RSS, blogs, social networking, bookmarking and more. It found that while libraries are experimenting with these technologies, staff development and understanding of student usage is still needed. Social software shows potential for outreach and information literacy if integrated thoughtfully into library services and teaching.
