A bit about E.L. Doctorow’s next novel, out this fall. . . . Also coming this fall: an unauthorized sequel to The Catcher in the Rye. Though, how serious an enterprise it is remains an open question. . . . An Australian book cover to treasure. . . . Leslie Gelb with a dispatch from a book tour, about, among other things, the commercial benefits to being wrong. . . . You’ve probably heard already, but the first Must-Miss book of next year has been signed up.
