Richard Rhodes came up with the idea of using the word, verity, as an alternate term to non-fiction, or more precisely "factual narratives." At first, I'd presume that only journalism and New Journalism (what now tends to be called creative non-fiction) would constitute this category. But, the brief essay found at the link below suggests that Rhodes includes Francis Bacon and Michel de Montaigne, both so crucial to our understanding of the term, essay. Wouldn't memoirs be included then, given how much essay and memoir overlap? History and biography are also certainly factual narratives. But if we include those within the verity category, why exclude philosophy, science, and other (mostly "social science") academic works? All this is to say that, on the web site that develops out of the "great books" project documented here, the texts, in addition to being split up chronologically and by language, will also be divided into four genre categories: poetry, theatre, verity, and fiction.
