@hannah @lanodan Well, you probably
can't if you're blind. The oldest braille book I've seen was a copy of
the Gospel of Matthew from the early 1930s. It wasn't in good shape
circa 1990 when I found it. Braille on thermoform has even less of a
lifespan.

OTOH I can download a book from Project Gutenberg produced 40 years ago
and read it with `less`.
