Online chat, text messaging, RSS feeds - we never imagined that these technologies would impact on information services in the ways they have, and we can only begin to imagine the greater changes that tomorrow will bring in the world of the virtual reference library. This collection is based on peer-reviewed lead papers from the Virtual Reference Desk Conference in Ohio, which have been developed, updated and refined for inclusion here. This is the pre- eminent forum in the world for the discussion and dissemination of the latest information on reference provision in a broad range of libraries, where leading scholars and practitioners in the reference information field offer knowledge and advice for embracing the future of reference services. This forward-looking volume: guides information professionals through new training and staffing models; looks at performance standards and evaluation tools; offers advice for serving new audiences; and, helps build collaborations and networks for reference services. Today's reference services are unable to deliver to customers the enhanced quality of information they demand, without access to such techniques. This cutting-edge text blends progressive thinking with practical applications and guidance, and is essential reading for all reference practitioners.
