Preconference Workshop presented at the Oregon Library Association Annual Conference, April 5, 2006 (Salem, Oregon)Once the purview of the geeks and the early adopters, social software applications like blogs and wikis have made their way into the mainstream. And it seems that every day more tools emerge: social bookmarking, citation-sharing, RSS and more. Just keeping abreast of new tools and what they do is a challenge for busy librarians. As our users find them, though, the challenges increase. More and more, these tools are being used in ways that force librarians to reconsider how we teach our students and patrons to find and evaluate information. How do weblogs fit into the publication cycle? How do social bookmark tags relate to subject headings? It is tempting to focus on the limitations of information published and organized with social, dynamic tools. Increasingly, though, simply dismissing these tools based on those limitations is impossible. Our users are finding the information they need in increasingly diverse places and sharing and storing that information in new and surprising ways. We owe it to our patrons to understand these tools and how they fit into the increasingly complex information landscape.
