They have in common that you can put books into both.

No. Its just the same without the limitation to books.

The idea of sharing: To be able to leave something and to pick something.

This is similar to a shelf I know from a pub. There you can put
everything you like which fits into it.

The difference is the size. The public bookcase are just a shelf and you
do not get in contact with money. May be the "trade" at tradeoff is
misleading. So we probably need another word.

One problem might be the specification. Since its only for books you
could use shop=books (which would be misleading - just an example). But
for no specific stuff I do not know at value.

> amenity=reuse
> reuse:books=yes

This could be a better alternative for tradeoff. I did not find a
wiki-article. Is there one?
