A free national library service providing recorded and braille materials is administrated by the National Library Service (NLS) for the Blind and Physically Handicapped in the Library of Congress. With the cooperation of authors and publishers who grant permission to use copyrighted books, NLS selects and produces full-length books and magazines in braille and on audiodisk and cassette. The reading materials are then distributed to a cooperating network of 56 regional and 92 subregional libraries that circulate them to eligible borrowers by postage-free mail. In the first section of the directory, the NLS network libraries and machine-lending agencies are arranged alphabetically by state. Each entry includes the library's address, phone and FAX numbers, operating hours, name of contact librarian, a description of the collection, assistive devices and special services offered, and the library's publications. Within each state the regional library appears first, followed by subregional libraries listed alphabetically by city. In several states two regional libraries have been established; in these instances, the specific service area of each library is shown. Regional libraries that also function as machine-lending agencies are identified by an asterisk. Separate machine-lending agencies (if any) are listed as the final entry for a state. The directory's second section is devoted to additional library resources available from 15 private organizations, e.g., the Braille Association of Kansas, Inc., which are arranged alphabetically by the name of the organization. These entries provide information on eligibility requirements, special media, subject coverage, and the organization's lending policies. Two appendixes, which make up more than a third of this publication, provide statistics on the readership and circulation, budgets, staff, and collections of the NLS network libraries. (MAB)
