This is a report on the three-year statewide study of school library facilities, collections, and services maintained by school districts and those maintained by county superintendents of schools, counties, or cities and made available to schools on a contractual basis. Data for the study were collected on questionnaires sent to every elementary, high school, and junior college library in California, in work sessions and interviews, and from special reports. Adequacy of school libraries was examined by comparing the collected data with approved library standards. Chapter I reviews the background and methodology of the study. Chapter II is an overview of California school libraries. Chapters III through V discuss elementary, high school, and junior college libraries respectively. Other topics covered in the study include: (1) county and district organization of school library services, (2) cooperation of community libraries and school libraries, (3) librarians for California schools, (4) The Education Code and school libraries, (5) effects of federal aid on school libraries, (6) consultant services, (7) new California programs, and (8) recommendations for improvement of school libraries.
