Question: How are materials received from and returned to the library? 

Answer: All books, magazines, catalogs, and equipment are sent to readers through the U.S. Postal Service as “Free Matter for the Blind” and may be returned the same way. Materials are sent by a network library with a removable address card, that when turned over and reinserted, will show the library’s name and address for return mailing.
