I'm very much ok with expanding the role of quality literary nonfiction in the K-12 curriculum, but lets also be realistic about the (lack of) urgency on this issue. There is not a crisis of people who are proficient readers of literary fiction but not of literary nonfiction. The modifier "literary" in this case means "pleasant and interesting to read." There may be a problem with complex texts, literary or not. And there may especially be a problem with complex non-literary nonfiction (e.g., a 800 page biology text). But it isn't like we have a nation of Moby Dick readers who can't make it through In the Heart of the Sea.
