The death of books? Maybe, depending on how narrowly you define "books." Take John Cheever's brilliant early (first?) short story, "Goodbye, My Brother."

(1) It's in Vintage Cheever, a book that Random House has made available online in full text.
(2) Here's a Google books version of the story, "Goodbye, My Brother": link.
(3) Here's the Amazon entry for Cheever's Collected Stories: link.
