U.S. Courts Design Guide
Access to the library must be located within the court security perimeter screened by
the U.S. Marshals Service (USMS). Libraries with limited staffing can have only
limited public access. The circulation desk, library staff offices, and study areas in
unstaffed libraries must have duress alarm devices. Systems for library materials
control may include a bar-scanner circulation system; some libraries with serious
book-loss problems also require book-detection systems.
The public entrance to the library must be provided a keylock. A keylock or electronic
access control from the library to restricted circulation must also be provided. In
addition, entrances to the circuit librarian's office, deputy librarian's office, rare
books/archives room, and enclosed storage require key locks.
The required reverberation time (see Table 8.3) determines the degree to which
acoustically-absorptive finishes must be used in the library. The entire library must be
acoustically isolated from other court functions, including noise-generating functions
within the library or adjacent spaces such as copier rooms or restrooms. Acoustical
treatment is required for all library ceilings, except in storage areas.
Heating, Ventilating, and Air Conditioning
HVAC controls must accommodate the library's hours of operation and
environmental requirements to protect the library's collection from temperature and
humidity fluctuations. In extreme climates, such as found in Florida or Alaska,
separate humidity and temperature controls may be required.
