Maybe if we all shout together? 1, 2, 3: An extra fee on the sale of used books discourages the reuse of books and encourages the destruction of trees, without benefiting anyone.

It's sad to me to think that most of the book donations a library receives would go straight to the library book sale. Right now, I'm thinking of a certain donation recently made to the library here, with the intent and hope that the books would be placed on the shelves.
