Among the Nonfiction Longlist are several that evoke the writer’s place and role in the exploration of ideas, and books that explore the natural environment. The authors are journalists, novelists, historians, poets, and naturalists. Included are a 2012 Pulitzer Prize-winning poet and a 1983 National Book Award Finalist for First Novel.
