I belong to a group that had a 'book challenge' to make a quilt from each book that you own. needless to say I didn't join the challenge, LOL
If you've gone thru and decided you don't want to keep the books (first make scan and copy anything that you want to keep for future use) you can:
1. post them on paperbackswap ... check it out
2. donate them to your local quilt guild
3. share/swap with friends
4. donate to local library
5. sell on ebay, garage sale etc.
6. sell on yahoo group SewItsForSale no charge to sell any sewing/quilt related items but you do have to 'join
7. sell here

I also have to purge some of my books, especially the older ones that no longer interest me.
