 World Records Book 2010-trade paperback book
   Trade paperback is an industry term that describes a book that is of better production quality. These books are produced in a larger size and offered at a higher price than a mass-market paperback format.

   (Mass-market paperbacks are generally cheaply made and printed on newsprint or other low-quality paper, which will discolor and disintegrate over time.)

    Trade paperbacks, on the other hand, meet a higher standard and are printed on high-quality paper.
