The outpouring of new instructional materials and techniques has resulted in a demand for instructional materials centers at the elementary school level. This handbook has been published to assist in planning and developing such a facility. The media center's usefullness to students, teachers, and administrators is outlined. The qualifications and job descriptions of the professional staff are set forth, along with a list of necessary supportive staff. It is pointed out that the quarters for a media center should be centrally located to students and teachers. Guidelines are laid down for the acquisition of an adequate supply of books, magazines, and other materials needed for both student and teacher use; the equipment necessary for the display and use of the materials is listed. An annual budget is proposed to provide sufficient funds to cover the costs of maintenance. Since there will be some material the teacher will want to develop himself, equipment necessary for such production is suggested. Standard library furnishings are suggested; specifications (height, width, depth, etc.) for various items are noted. A 3-phase program for each aspect of the center's development is outlined. A bibliography supplements the report. (JY)
