This report covers the research activities undertaken during the first phase of a project, the purpose of which were (1) to determine actual requirements for library resources by elementary and secondary school students in Philadelphia and to evaluate existing library resources in terms of needs and standards and (2) on the basis of these data, to outline the respective roles of the several school systems and the public library system in providing needed resources, including joint planning of services, facilities, and technological innovations. Pre-elementary, elementary, and secondary students in the public, Archdiocesan, private and independent schools in Philadelphia were included in the study. Phase I activities covered by the report are project organization, project planning and research design, design and pretest of data-gathering instruments and procedures, evaluations of the pretests, sampling methodology for field survey of approximately 60 schools, and school enrollment estimates by system and grade-group for use in projecting student library resource requirements to 1990. The major instruments which were designed, pretested, and evaluated in Phase I (student questionnaire, teacher questionnaire, school library questionnaire, public library questionnaire, and school and public library use checklists) are included in document ED 031 611, a supplement to this report.
