So when digital evangelists prognosticate about the future of publishing, as they love to do, and about what “needs” to go away, serious nonfiction is now one of the first things I think about. Maybe it’s because I’m getting older and want to read more of it and notice twentysomethings have little perceived patience for weighty tomes. Maybe it’s because I’d rather have pragmatic conversations about what categories are best suited to digital — genre fiction obviously, certain commercial strains of literary fiction, basically any book that needs to have a completed manuscript done before it’s shopped around, or can be finished very quickly post-proposal — and which ones won’t be. Maybe it’s because the very institutions that support serious nonfiction are themselves in more financial trouble than they used to be.
