For years, Bradbury tried to prevent the publication of Fahrenheit 451 as an e-book. He told the New York times that electronic books "smell like burned fuel" and called the internet "a big distraction".
"It's meaningless; it's not real. It's in the air somewhere," he said.
But he relented in 2011, when his publishing deal was renewed. His agent said: "We explained the situation to him, that a new contract wouldn't be possible without e-book rights. He understood and gave us the right to go ahead."
Bradbury also wrote several works for film and television. He wrote the screenplay for John Huston's film Moby Dick and scripts for many TV series, including Suspense, The Alfred Hitchcock Show and The Twilight Zone.
Bradbury was passionate about literature. In 2008, he told The National Endowment for the Arts: "If you know how to read, you have a complete education about life, then you know how to vote within a democracy.
"But if you don't know how to read, you don't know how to decide. That's the great thing about our country - we're a democracy of readers, and we should keep it that way."
