Books can come in many different forms, from USED to softcover, COOKED to popup, ontape to largeprint, and pocketsized. USED books are those that have been previously owned and may show signs of wear and tear. Softcover books are bound with a flexible paper cover instead of a hardcover. COOKED books are those that have been printed on demand, usually from an online source. Popup books are those that contain three-dimensional elements that pop up when opened. Ontape books are those that have been recorded onto audio cassette tapes. Largeprint books are those that have been printed with larger than normal font sizes, making them easier to read. Pocketsized books are those that are small enough to fit into a pocket or purse.
