Jason Epstein, 93, a publishing innovator and bon vivant who helped put the classics in paperback, co-founded The New York Review of Books and worked with such novelists as E.L. Doctorow, Vladimir Nabokov and Philip Roth, died Friday “surrounded by his books” at his home in Sag Harbor, New York, said his wife, the author and former New York Times journalist Judith Miller. The cause was congestive heart failure, she said. Among the many books edited by Epstein: Doctorow’s Depression-era novel “Billy Bathgate,” Jane Jacobs’ classic of urban studies “The Death and Life of Great American Cities” and Mailer’s CIA epic “Harlot’s Ghost.”
