Chapter 8: Central Court Libraries
Temperature, Ventilation, Air Changes, and Humidity
See Table 8.4 for specific criteria.
The rare book/court archives room and the microform storage area require the
following special, more constant humidity levels:
Microforms: 30%
Bookstacks: 40-50%
Lighting
Natural Lighting
Computer Assisted Legal Research. CALR stations should not be located where
there is a glare from natural light.
Bookstacks. Natural light is undesirable for bookstacks due to the damaging effects of
sunlight.
Rare Book/Court Archives Room. Natural light is undesirable due to the damaging
effects of sunlight.
Study Spaces. Windows allowing an exterior view and natural light are highly
desirable. For enclosed study rooms, interior windows are preferred, since users may
need to darken the rooms to view video. Interior windows also allow others to
determine whether the rooms are occupied.
Staff Offices. Natural light is desirable for all offices. Interior windows are necessary
so staff can monitor library activity.
Technical Services Area. Natural light is desirable, assuming excessive light is
controlled. Interior windows must be provided for viewing adjoining staff areas.
Microform Area. Natural light is undesirable in the microform area, since readers
require a controlled-light environment. Interior windows with a view of library areas
must be provided if the area is enclosed.
