"The National Library Service for the Blind and Print Disabled, part of the Library of Congress, is a free braille and talking book library service for people with low vision, blindness, or a disability that prevents them from using regular print materials. One way NLS fulfills its mission is via these neat Braille eReaders, which are much more portable than a regular braille book and have internal storage for a whole personal library!"
