Amazon doesn't remove old book listings

Just so you know both as a writer and as a buyer to be careful when you buy a book at Amazon. You may be buying an outdated edition because they don't take down the old ones. This article explains what you can and can't do about that.

When an author publishes a brand new edition of their book, or when they move their book from one publisher to another, or even when they get the rights back to their book and decide to self-publish, they are often frustrated to learn that Amazon will not remove the old version of their book from Amazon.com. Unless there is a copyright or trademark dispute, Amazon will leave a book up for eternity and they have legitimate (and legal) reasons for doing so.
