This handbook is an expanded version of an original guide written as a basis for orientation and training of new children's librarians and allied personnel. It puts into one place the basics of library service to children, with an emphasis on the practical rather than the theoretical. Among topics covered are: (1) roles and responsibilities of children's librarians; (2) understanding children; (3) planning, developing, and maintaining a collection of both print and nonprint materials; (4) an approach to the problems of censorship; (5) implementing creative programs, such as storytelling, puppetry, and creative drama, using a variety of activities and media; (6) administration of and current issues in children's services; (7) publicity and public relations; and (8) relationships with other agencies and organizations. The book can serve as a refresher for practitioners, a guide for trainees, or a text for students. (SLD)
