Amazon invited some unflattering literary analogies earlier this summer when it remotely erased unlicensed versions of two George Orwell novels from its customers’ Kindle reading devices.

Jeffrey P. Bezos, Amazon’s chief executive, apologized to customers for the deletions in July. And late Thursday, the company tried to put the incident behind it, offering to deliver new copies of “1984” and “Animal Farm” at no charge to affected customers.

Amazon said in an e-mail message to those customers that if they chose to have their digital copies restored, they would be able to see any digital annotations they had made. Those who do not want the books are eligible for an Amazon gift certificate or a check for $30, the company said.
