Hi,
Due to diabetes, my father was legally blind for the last ten years of his life, so I ran into this ...
Check with your state library. Most have a connection to the Library for the Blind ...
There is an application that must be filled out and sent in (including certification from your Doc saying you are legally blind).
Then a list of all available books are sent to you, and you order what ones you like to read ... and they are sent to you basically free ... I don't believe there is even a charge for shipping! (If there is, my parents never mentioned it ...)
Wishing you all the best ...
