What is a PortaBook?
A PortaBook is a braille file on disk (in contracted, or Grade 2, braille). All our current titles, and most of our past ones, are available in PortaBook format, except those with tactile graphics. PortaBooks are designed primarily to be read on a portable braille reading device, but they can also be embossed with a braille embosser, or accessed with a computer and braille display or braille-aware notetaker.
