Accessible Digital Media Guidelines Guideline D: Digital
Publications Accessible electronic books (e-books), digital
talking books (DTBs) and on-line, HTML-based textbooks and
training materials can bridge the gap that often exists for
students or workers who require adapted reading materials, such
as braille or audio recordings. Electronic versions of learning
materials, if properly designed, can make curricular content
equally accessible to all learners, at the same time. Provide
access to digital publications. While there are established
digital talking book services, braille-production and tactile-
graphic facilities that specialize in producing educational
materials for blind children, major obstacles exist that force
many students to begin class without the braille version of
their books. At the K-12 level, teachers must identify all the
texts that will be used in class well ahead of time and request
adapted versions. At the post-secondary level, students must
anticipate their own needs for adapted texts
