Several writers of notable books have donated "marked up" copies of their book, and they are being auctioned for First Books (www.firstbook.org). The authors have marked up the books with several notes and comments in the margins of the book with random thoughts and observation. More details on the auction can be found here.
The first book up for bid is "Quiet, Please: Dispatches from a Public Librarian" by Scott Douglas. Bidding starts at 5 dollars, and all money goes to First Books.
