This study was designed to gather information about the views of librarians and the public concerning materials and services provided for children in the public libraries of the South Central Regional Library System in Ontario. Questionnaires distributed in each of the 13 communities served by the system asked about the perception of the provision of and the importance of current and possible future services. Questionnaires were distributed to all librarians in the public libraries, and to a sample of principals, teachers, nursery school teachers, and library users; the questionnaires administered to librarians also included items about the services offered to the libraries by the regional system. An analysis of the more than 500 questionnaires returned showed that differences in the perception of services exist among the three groups: parents and teachers are more likely than librarians to view the provision of audiovisual materials, materials and services for very young children, and parent-child programs as very important. All groups agree on the importance of the traditional services of picture books, story hour programs, and help with school projects. Included with the report are 59 tables of data, the survey instruments used in the study, and selected comments of respondents. (Author/JD)
