Do you have multiple copies of any of your books?
If so, why? Absent-mindedness? You love them that much? First Editions for the shelf, but paperbacks to read?
If not, why not? Not enough space? Not enough money? Too sensible to do something so foolish?
Don’t forget to leave a link to your actual response (so people don’t have to go searching for it) in the comments—or if you prefer, leave your answers in the comments themselves!
And–you can play any time; it doesn’t have to be Thursday!
