The US Department of Justice  has filed a new document in the Apple eBook antitrust lawsuit. The filing includes an email sent from Apple’s founder Steve Jobs to Rupert Murdoch, head of News Corporation, the owner of HarperCollins, one of the publishers named in the original complaint.

The Verge has the story: “In the email, Jobs told Murdoch he could either continue to have Amazon price ebooks at $9.99, or ‘throw in with Apple and see if we can all make a go of this to create a real mainstream ebooks market at $12.99 and $14.99.’”

While all of the five publishers in the eBook collusion have settled with the DOJ and agreed to terms that would prevent future collusion, Apple continues to fight the case.
