It  will not be helpful to go to the Access Board for this information. ADAAG does not provide information or technical requirements on labels and brochures.  It only provides information on technical requirements for permanent signage.

There are several resources for producing accessible, usable and readable labels and brochures. The following are the best resources:
Labeling and Exhibit Design

"Everyone's Welcome: The Americans with Disabilities Act and Museums" and "Standards Manual for Signs and Labels"
American Association of Museums
1575 Eye Street, NW, Suite 400

"Smithsonian Guidelines for Accessible Exhibition Design"

Room 1239 MRC 426
Washington, DC 20560
