John Irving has been nominated for a National Book Award three times—winning in 1980 for the novel The World According to Garp. That book, and a number of others, including The Cider House Rules, for which he won the 2000 Oscar for Best Adapted Screenplay, have been turned into films. Other popular Irving novels include A Prayer for Owen Meany and Avenue of Mysteries. In 2001, he was elected to the American Academy of Arts and Letters.
