In the work of canon-building, nonfiction tends to get short shrift. While memoir has gained a foothold in the literary conversation, narrative and reported nonfiction tend to be ignored. It can be easy to dismiss these forms as the worthwhile but fundamentally unliterary assemblage of facts into paragraphs. Yet what reader hasn't had her mind expanded, her heart plucked, her conscience stirred by a nonfiction book? The responsibility the writers of such books take on, to arrange the facts of the world into a form that makes sense of its tumult, can produce in the reader a kind of clarity of thought that no other genre can match.
