Personally I rather like the idea of the book tree we have in a nearby park.
It's a tree that was about to be felled and was cut about 2 yards above ground and then carpenter cut protected recessed that each hold a book.
You're supposed to take a book from the tree and leave one you don't want any more.
It's just next to the library and they use their retired books to keep it filled when people forget the part about leaving a book when you take one.
Reductionist and proud of it.
Being ignorant is not so much a shame, as being unwilling to learn. Benjamin Franklin
Chase after the truth like all hell and you'll free yourself, even though you never touch its coat tails. Clarence Darrow
A person who won't read has no advantage over one who can't read. Mark Twain
