This booklet provides guidelines and suggestions for planning school library media facilities. The intended audience is library media specialists; however, it is expected that administrators and architects may also find it useful. The importance of helping the architect understand the school media center's unique mission and relevant educational specifications--e.g., activities related to teaching and learning, patterns of use, and space requirements--is discussed, and checklists for educational specifications and monitoring progress are provided. A detailed discussion addresses the functions and relationships of major areas within the media center, e.g., circulation, reading areas, and computer laboratories; describes New Hampshire's minimum space requirements; and presents recommended space allocations in tabular form. General aspects of design that encourage easy access to information and services are outlined. Specific design considerations are offered for acoustics, color and signage, environmental control, handicapped access, lighting, safety, security, traffic flow, technology and communications, visibility, weight, and windows. Specific types of furniture and furniture arrangements are suggested, and tips for moving a library media collection from an old facility to a new one are provided. A narrative description of an elementary school library media center is appended together with examples of floor plans for elementary, middle, and high school library media centers.
