A collection of original essays, case studies, and research reports is presented on the problems, hopes, and techniques of instructing library users and nonusers, from the kindergartener to the postschool adult, in the effective use of libraries and their resources. First there is a comprehensive overview of the research to date on library user education. Articles in Part 1 probe the special problems in dealing with children and young adults, undergraduates, and the postschool adult. In Part 2, authors explore the significant and often neglected role of the teacher in educating students to use the library. Various approaches to library-use instruction are presented in Part 3, "Implementation and Evaluation of Library-Use Instruction Programs." Finally, the library school's responsibility in preparing librarians who can successfully introduce the library to potential users is considered. (Author/LS)
