It is 2am. A professor wakes up with a new direction for her research; she must immediately learn about bioethics. In a dorm a student is finally ready to begin a paper on Cuba. Where do they turn? The library web site presents them with a bewildering array of resources and no librarian on hand to serve as intermediary. How can librarians facilitate research in their absence? What interfaces can be designed to educate users in their search? What metadata is needed to enable accurate retrieval? What is the librarian’s role in the increasingly indirectly-mediated information-seeking environment? Can the reference interview be effectively translated into a search interface? This paper describes a step towards resolving these issues by creating an on-line tool to assist users in selecting the database(s) most germane to their research needs.
