Braille is "a series of raised dots that can be read with the fingers by people who are blind or whose eyesight is not sufficient for reading printed material…. Braille is not a language. Rather, it is a code by which languages such as English or Spanish may be written and read" (Source: American Foundation for the Blind).

Audio formats include tapes, CDs, MP3 files, text-to-speech programs, and other auditory alternatives to printed texts.

Large Print format provides the same content as standard print, only in larger font or page sizes to help those with visual impairments read more easily.

E-text (electronic text) files include Microsoft Word and other file formats produced by word processing programs, such as rich text files (RTF), ASCII, HTML, and Digital Talking Books. Such files can be transformed into accessible forms by users by varying font size, using text-to-speech tools, etc.
