A Guide to the Librarian's Responsibility in Achieving Quality in Lighting and Ventilation.
Mason, Ellsworth
Library Journal, v92 p201-206 Jan67
Quality, not intensity, is the keystone to good library lighting. The single most important problem in lighting is glare caused by extremely intense centers of light. Multiple interfiling of light rays is a factor required in library lighting. A fixture that diffuses light well is basic when light emerges from the fixture. It scatters widely, sending out multiple rays in many directions. To get the kind of interfiling needed, this effect of a single fixture must be multiplied as many times as possible. The character of the surround walls, floor, and any furniture or equipment within the lighted space must also be considered. The darker they are, the lower the intensity and the poorer the quality of light that will result from any given ceiling source. A good ventilation system is as important as good lighting in effecting the patron's reaction to a library. Good quality in air distribution is more important than temperature settings. Basic acquirements of a good quality ventilation system for a library are simple--it must distribute air throughout the building at the proper volume, at the proper temperature, from a proper distance, and at a suitable noise level.
