One of the features of the upgraded Kindle is that it can read a book out loud to you, using a canned computerized voice similar to the text to speech systems available on many current computers.
Upon hearing of this, the Authors Guild told the Wall Street Journal "They don't have the right to read a book out loud. That's an audio right, which is derivative under copyright law."
Faced with pushback (including the suggestion that perhaps the Authors Guild would like to ban all reading aloud of books), the Guild retrenched, suggesting that publishers should consider forcing Amazon to add restrictions to books that could block access to the read-aloud feature.
This is absurd. Book owners can buy paperback books, and rebind them into hardcovers; companies like Brodart sell this service to libraries. It's as if the Authors Guild was trying to put Brodart out of business, claiming that rebinding paperbacks would infringe on their exclusive rights to sell hardcover rights.
There's been a lot written about this, but my favorite is Neil Gaiman's take.
"When you buy a book, you're also buying the right to read it aloud, have it read to you by anyone, read it to your children on long car trips, record yourself reading it and send that to your girlfriend etc. This is the same kind of thing, only without the ability to do the voices properly, and no-one's going to confuse it with an audiobook. And that any authors' societies or publishers who are thinking of spending money on fighting a fundamentally pointless legal case would be much better off taking that money and advertising and promoting what audio books are and what's good about them with it."
