Yes, I know that when you want to make updates to your novel you can upload the new version to replace the old. . . .
For research purposes, though, I'd like to know your experiences with "unpublishing" a title from BN or Amazon entirely.
How long did the book take to disappear? Did it not disappear at all (i.e. were you left with a "phantom" book connected to your account forever)?
Did you try to upload it at a later time and have trouble?
Any experiences appreciated.
