This primer for Mississippi school librarians is designed for use as a planning guide by teachers, librarians, administrators, and supervisors involved in developing school library programs. The ten chapters of the bulletin cover: philosophy of the school library; standards; school library facilities; library collection development, including sorting, weeding, and book selection; acquisitions, including budgeting, ordering, and receiving materials; organizing the library collection; hints on classification and cataloging; organizing for better library service; the role of the library in the school; evaluating the elementary school library program; and evaluating the secondary school library program. General information, specific suggestions, and sample forms for organization and evaluation are included. (This manual which evolved over several years as a result of workshops, seminars, and conferences held in the various schools and colleges in Mississippi, has been in use since 1967.) (THC)
