Courtesy of Joanne Jacobs, we read that Ray Bradbury's Fahrenheit 451 was itself censored! Bradbury himself:

There is more than one way to burn a book. And the world is full of people running about with lit matches. Every minority, be it Baptist / Unitarian, Irish / Italian / Octogenarian / Zen Buddhist, Zionist/Seventh-day Adventist, Women's Lib/Republican, Mattachine/FourSquareGospel feel it has the will, the right, the duty to douse the kerosene, light the fuse. Every dimwit editor who sees himself as the source of all dreary blanc-mange plain porridge unleavened literature, licks his guillotine and eyes the neck of any author who dares to speak above a whisper or write above a nursery rhyme.

Fire-Captain Beatty, in my novel Fahrenheit 451, described how the books were burned first by the minorities, each ripping a page or a paragraph from the book, then that, until the day came when the books were empty and the minds shut and the library closed forever.

"Shut the door, they're coming through the window, shut the window, they're coming through the door," are the words to an old song. They fit my lifestyle with newly arriving butcher/censors every month. Only six months ago, I discovered that, over the years, some cubby-hole editors at Ballantine Books, fearful of contaminating the young, had, bit by bit, censored some 75 separate sections from the novel. Students, reading the novel which, after all, deals with the censorship and book-burning in the future, wrote to tell me of this exquisite irony. Judy-Lynn Del Rey, one of the new Ballantine editors, is having the entire book reset and republished this summer with all the damns and hells back in place.

I hope they will highlight the restored words and sentences and paragraphs.

UPDATE: This was written by Bradbury in 1979.
