A chapbook is a pocket-sized booklet. The term chap-book was formalized by bibliophiles of the 19th century, as a variety of ephemera, popular or folk literature. Many different kinds of literature have been made into chapbooks, such as pamphlets, political and religious tracts, nursery rhymes, poetry, folk tales, children's literature and almanacs. When illustrations are included in chapbooks, they are considered popular prints. The term is derived from chapmen, chap coming from the Old English cÃ©ap meaning deal, barter, business, a variety of peddler, who circulated such literature as part of their stock.
