The document summarizes the changing landscape of libraries and information services for researchers. It discusses how researchers use information at different stages of research, from identifying existing knowledge to disseminating new findings. Researchers are increasingly using blogs, listservs, and research colleagues to discover information, rather than traditional library resources. The role of libraries, publishers, and other information providers is evolving as open access increases and data sharing becomes more important. Sustainable models are needed to meet researchers' changing needs.
