Foreword PLANNING MATERIALS CENTERS has been designed as a guide for helping architects, administrators, supervisors, teachers, and school materials personnel determine essential facilities for housing instructional materials and equipment ade- quate for the instructional program of the total school.

Since each renovation is unique, this Guide does not contain a section on remodeled quarters. However, in planning for remodeled quarters those concerned should consider the recommendations for adequate quarters and equipment as outlined in this Guide for new build- ings in the same type school. In their plans, then, they can imple- ment and adapt these recommendations in terms of the space and other facilities that are available in the remodeled quarters. The Guide has been divided into separate sections for ele- mentary, secondary, and twelve-grade materials centers so that persons using it will have no difficulty in distinguishing recom- mendations for each type of center.

The placement of doors serves only to orient other adjoining rooms and service areas; the placement
