A group of 40 elementary school librarians in the greater Phoenix area of Arizona were invited to participate in a study of the effects of an experimental school library motivational program on library use, library attitudes, and reading attitudes of elementary school students. Librarians at 13 schools participated, with 11 completing the study. Each librarian provided a program of specific library activities taken from "Procedures for Library Study" (Everett, 1982) for sixth grade students, with a control group of students denied any exposure to the special library program. The effects of the program on elementary school students' classroom-related and non-classroom-related (social, study, or research) library use were large, and generalizable to the population of schools of which the 11 studied are representative. Students' attitudes toward the school library/librarian and reading also seemed to improve as a consequence of the program, although this result was suggestive rather than definitive. Although girls made greater use of the library and tended to have more favorable reading attitudes, the treatment appeared to have an equal effect on both sexes. The participating school librarians were very favorable in their evaluation of the program. A seven-item bibliography is provided. (ESR)
