The National Library
Service for the Blind and Physically Handicapped (NLS), established
in 1931, operates under the jurisdiction of the Library of Congress.
The Illinois NLS network is administered by the Illinois State
Library and consists of the regional library in Springfield and
four sub-regional Talking Book Centers located throughout the state.
Talking books and braille materials are mailed by the U.S. Postal
Service as as "Free
Matter for the Blind or Handicapped" at no cost to eligible users.
The regional center acts as a liaison with NLS, and maintains
a reserve collection of braille and talking books.
