Paperbacks
Extracted from the Wikipedia article Paperback.
Inexpensive books bound in paper have existed since at least the 19th century in such forms as pamphlets, yellowbacks and dime novels. Modern paperbacks can be differentiated from one another by size. In the United States, there are "mass-market paperbacks" and larger, more durable "trade paperbacks". In the United Kingdom, there are A-format, B-format, and the largest C-format sizes.
