ADAAG Manual

Libraries [8]

Reading and Study Areas [8.2]

Access is required to at least 5% of fixed tables and study carrels. Recommendation: Specifications in 4.32, including clear passage for accessible routes, knee clearances and surface height (34 inch maximum) should be considered for movable furnishings as well.

Check-Out Areas [8.3]

Check-out counters at accessible lanes are held to a maximum surface height of 36 inches. Also required:

• an alternative route at turnstiles

• accessible gates [4.13.3] on accessible routes

• access through (or around) book security devices (see page 135)

Card Catalogs and Magazine Displays [8.4]

Specifications are provided for magazine racks and card catalogs but access is also important at computer terminals available to the public for library searches and other information. Requirements for fixed counters and tables [4.32] specify a surface height (34 inches maximum) and knee clearance below appropriate for extended use as a writing/work surface. Where the period of use is likely to be brief, or where standees are to be accommodated as well, requirements in 7.2 for sales and service counters (36 inch maximum surface height, knee and toe space for forward approach optional) may be appropriate as an alternative. The preferred maximum reach height for card catalogs is 48 inches (recognizing that users may be lifting or manipulating card drawers).

Stacks [8.5]

Elements fixed to stacks, such as ladders, cannot reduce the minimum passage width nor should signs or other elements between 27 to 80 inches above the floor project more than 4 inches into aisles. Recommendation: Consider accessible circulation around stacks so that people using wheelchairs need not backup for long distances. T-shaped turning space will provide space for wheelchair maneuvering.

Recommendation: Dimensions for turns around obstructions in 4.3.3 (ADAAG Figure 7) provide minimum space for maneuvering around stacks where a cross aisle at the end of stacks is not provided.
