My local library has a large permanent book sale area. Books are categorized and shelved like the rest of the library, making it easy to search for a particular author. I still listen to music on CDs while I quilt and they always have a large selection for $1 each. I have found a lot of new artists I wouldn't have tried otherwise. If I don't like them I just donate them back again. Of course, I've also found a lot of music I loved back in the 70s when I was young.
