Do you have a Latin student who is blind or dyslexic who would benefit from having a digitally recorded textbook? Recording for the Blind and Dyslexic is a national, non-profit organization that provides educational materials to students with severe vision impairments (such as blindness or dyslexia). Subscribers to RFB&D must have a documented disability in order to use their library. Details are on their site.
You'll be happy to know that they have several popular Latin textbooks in their library, including the Cambridge Latin Course, Ecce Romani, and Jenney's Latin.
