A friend just bought a Nook and had a question about how to remove the sample books. I figured I'd post the instructions, since I'm sure the question will come up again, either on a message board, or when my mom gets a Nook later this year. =)
Another thing you can do is archive your books. All you have to do is highlight the book you want to archive and go to item details hit archive. This will take it off of your nook but you still have access to this title should you wish to redownload it at a later time. You can change your views so that archived books are not visible. This saves space on your nook too!
