The Braille alphabet is a pattern of raised dots. People with limited vision use it to communicate in writing. It is read by sense of touch and written by machine such as typewriter, computer, or printing press.

The National Braille Press, located in Boston, Massachusetts, is a nonprofit organization that publishes books in Braille. They produce a variety of materials in including popular titles, periodicals, government publications, and educational materials.

The production process starts with transcription - creating computer files of the text. Source material is often available in electronic form, but scanning or manual entry are sometimes necessary. The text must also be edited to follow Braille conventions.

A metal plate is created from the transcribed file, and one page is pressed for proofreading.
Proofreaders check each page for errors.

Modified letterpresses are used to create braille imprints. After printing the pressed pages are collated. Collated books are checked by hand.

Books are bound together using staples, pins, or metal rings. Finally, they are packed in boxes, labeled, and ready for shipping.
