When looking for schoolbooks for the severely dyslexic little brother of a friend we tried looking for audio books. Turned out there was an organisation which used to deal with that here. Notice "was". For schoolbooks which had no audio book available from the publisher they'd got teachers who volunteered to record audio books for blind students. Guess what the publishers thought of that. Now they aren't allowed hand out recordings to blind students and the publishers aren't interested in making or distributing any since the market is so small.
