Britannica online academic edition, Nov. 14, 2012 (nonfictional prose: any literary work that is based mainly on fact, even though it may contain fictional elements; examples are the essay and biography; the term nonfictional prose literature here designates writing intended to instruct (but does not include highly scientific and erudite writings in which no aesthetic concern is evinced), to persuade, to convert, or to convey experience or reality through "factual" or spiritual revelation; one feature common to most authors of nonfictional prose is the marked degree of the author's presence in all they write; the basic modes of writing--the descriptive, the narrative, the expository, and the argumentative--are found in both nonfictional literature and in fiction)

The nonfictionist's guide : on reading and writing creative nonfiction, 2008: pp. ix-x (when I say "nonfiction" in this book, I mean what we usually refer to as "creative nonfiction" or "literary nonfiction." Those terms are slippery enough in their own rights that I'll mostly avoid them. Here, nonfiction, the fourth genre, refers to such forms of writing as the personal or familiar or reflective essay, the memoir in short or long forms, personal narrative reportage of travel and place and exploration and investigation; nonfiction can be identified by these common elements: personal presence, self-discovery and self-motivation, flexibility of form, veracity, and literary approaches) pp. 3-4 (the term "creative nonfiction" is too oppositional, implying a need to distinguish it from "non-creative nonfiction"; Nonfiction, n. : 1. the written expression of, reflection upon, and/or interpretation of observed, perceived, or recollected experience; 2. a genre of literature made up of such writing, which includes such subgenres as the personal essay, the memoir, narrative reportage, and expressive critical writing and whose borders with other reality-based genres and forms (such as journalism, criticism, history, etc.) are fluid and malleable; 3. the expressive, transactional, and poetic prose texts generated by students in college composition courses; 4.
