Jacket 34 - October 2007
Wikipedia - "A chapbook is an early type of popular literature printed in Early Modern Europe. The tradition of chap-books arose in the 16th century, as soon as printed books became affordable, and rose to its height during the 17th and 18th centuries. Many different kinds of ephemera, popular or folk literature were published as 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 chapbook is also in use for present-day publications, usually poetry, of up to about 40 pages, ranging from low-cost productions to expensive, finely produced editions."
