In George Orwell’s “1984,” government censors erase all traces of news articles embarrassing to Big Brother by sending them down an incineration chute called the “memory hole.”
On Friday, it was “1984” and another Orwell book, “Animal Farm,” that were dropped down the memory hole — by Amazon.com.
In a move that angered customers and generated waves of online pique, Amazon remotely deleted some digital editions of the books from the Kindle devices of readers who had bought them.
Amazon effectively acknowledged that the deletions were a bad idea. “We are changing our systems so that in the future we will not remove books from customers’ devices in these circumstances,” Mr. Herdener said.
Digital books bought for the Kindle are sent to it over a wireless network. Amazon can also use that network to synchronize electronic books between devices — and apparently to make them vanish.
