This document provides guidelines for planning the physical facilities that house learning resources centers. Data for the report was collected over a 12-year period, with input from personnel at learning resources centers throughout California. Discussion is broken up into the following sections: (1) development of the guidelines, which includes information on space allocation, user stations, work space and service areas, materials, equipment and instructional services, and square footage per day-graded student; (2) guidelines for planning the learning resources center, including suggested apportionment and space relationships, as well as print, non-print and related instructional services; and (3) application of the guidelines, which provides self-appraisal instruments and techniques for assessment. Appended are background perspectives, as well as a graph and table illustrating the allocation of square feet computed on the basis of day-grade students. (AS)
