Three duplicates. Don't know how two of them got there (the other I can easily imagine I just grabbed from a .25/each bin at the New York is Book Country sale).
Found thirteen other books I'm actually - sit down before continuing to read - giving away.
Did not find a book I know I own (it's in the catalog) and I swear Thing One decided I wouldn't miss.
As you can see, I have problems getting rid of books. Not this guy. Although I do think it's a little extreme, don't you? Maybe someone can help him find a better way to get rid of his stock?
