The document discusses the five stages of the reference interview process as outlined by the Reference and User Services Association (RUSA): approachability, interest, listening/inquiring, searching, and follow-up. It provides examples of how a reference librarian would apply each stage in helping a patron with their research on cloud formation and precipitation prediction. The librarian asks open-ended questions to learn about the patron's previous research, suggests additional databases to search in, and ensures the patron knows how to contact them if other questions arise later. Following best practices for reference interviews helps librarians understand patrons' needs and provide the most effective assistance.
