The American Printing House for the Blind (APH) was established in 1858 and manufactures braille, large print, audio, and tactile graphics, together with a variety of educational and daily living products.
APH is using a specialised DTD (Document Type Definition) to find a solution to a long-standing problem with creating text books in two or more accessible media. The company is writing software that lets it use one source file to create both a large print and a braille version of a textbook. The DTD is, of course, able to work with digital audio, too, and APH will produce some recorded books using this media.
