(2) Circulation Within Room.
Stack aisles should be large enough to allow materials
to be viewed easily. The recommendation face-to-face
spacing between book stacks is 3 feet.
F. Environmental Conditions.
(1) Lighting.
a. Different kinds of lighting should be used
throughout the library to satisfy different visual task
requirements. Specially designed lighting systems should
be used in the stack, carrel, and reading areas and at
the circulation desk. A lighting designer or engineer
should recommend proper lighting systems during the
design phase.
b. The general required lighting level is 50 foot-
candles.
(2) Storage.
There should be enough storage to accommodate both
existing and future learning resources. (Figure 4-52).
G. Furniture.
Library furniture should be attractive and comfortable.
If the library is supervised, there is less chance that
students will abuse the furniture. Therefore, couches
and cushioned chairs can be used in specified reading
areas.
H. Interior Design.
