This paper outlines the history, functions, administration, and current focus of school library services in Hawaii, which is the only state in the United States with a library staffed by a trained librarian in every public school. Its first school library was established in 1882. Elementary school libraries developed concurrently with secondary school libraries and these libraries have always included both print and nonprint materials in their collections. School library centers in Hawaii perform a triple function as materials, instructional, and service centers, with a wide range of activities grouped under these functions. Since 1959 the Director of School Library Services in the Department of Education has provided the leadership for school library development. The Office of School Library Services, in conjunction with the University of Hawaii's Graduate School of Library Studies, is responsible for providing workshops and seminars to upgrade school librarians' skills. The office also publishes guides and manuals and serves as a consultant for advising and assisting school librarians and administrators. Placement of the School Library Services Program under the Office of Instructional Services in 1977 (rather than under the State Librarian) has resulted in increased emphasis on library skills instruction in Hawaii's elementary and secondary schools and the integration of this instruction with the regular school curriculum.
