Going to the effort of making materials accessible to everyone should not go unpublicized.  Be sure to tell people these CDs or files exist, where to find them and how to offer them.  Visibility of accessible materials presents your company or organization a chance to be seen as proactive and inclusive.  Furthermore, an environmentally friendly image can also be promoted.  Be proud of the steps taken to make sure everyone has equal access to your information and let that pride be seen in how you utilize your accessible materials.
