Novel

A market of literature in the modern sense of the word, that is a separate market for fiction and poetry, did not exist until the late seventeenth century. All books were sold under the rubric of ``History and politicks'' in the early 18th century, including pamphlets, memoirs, travel literature, political analysis, serious histories, romances, poetry, and novels.
