337 Library, Public

This occupancy refers to structures used to provide books and services to meet the reading and research needs of a community. Variations can be found in the design, due primarily to the amount of service programs and the amount of people serviced by the library.

Typically, libraries can be subdivided into a number of different sections. Each library may not have all segments due to its design characteristics and services offered.

Commonly, there are control areas, staff work areas, reading areas, collection areas and restrooms in most libraries. The better quality libraries may have, in addition to the sections specified, study cubicles, conference/meeting rooms, audiovisual facilities and various processing, cataloging and exhibiting areas.

Exteriors have special features and designs in the better qualities that include marble, special veneers, ornate entries, and metal and glass panels. Lower qualities are plain with little, if any, ornamentation.

Interiors of the better quality libraries are very similar to those found in large cities. Plaster or drywall finish with wallpaper or paneling, carpet, vinyl or terrazzo on the floor and high-cost lighting are frequently found.

At the average quality level are small college or city libraries and some branch libraries. Lower cost buildings are typically very plain small branch libraries.

The following are not included in the costs: Cabinets, counters, reader tables, book stacks and seating.

For school libraries, use occupancy 360 (Library, Media Center) or 372 (Library, College).
