At the last library used book sale we had over 13 boxes of paperback books left. No one wanted them even when offered for free. We called nursing homes, prison, and missions. We took all the leftovers to Salvation Army. The library has a donation center for used books and volunteers sort and box them for the sales. The last few sales not many books were sold, even the newer ones. It's like the library is the middle man, receiving the books to deliver to the donation center.
