A mass market paperback (MMP) is a small, usually non-illustrated, and inexpensive bookbinding format. They are commonly released after the hardback edition, and often sold in non-traditional bookselling locations such as airports and supermarkets, as well as in traditional bookstores.
Paperback editions of books are issued when a publisher decides to release a book in a low-cost format. Cheap paper, glued bindings, and the lack of a hard cover contribute to the inherent low cost of paperbacks. It doesn't refer the title, rather, it means that the book is printed with a soft, flexible cover rather than hard binding. Paperback would be the alternative to a hardcover book. Hardcovers are generally more expensive, and books are normally released as hardcover before being printed in paperback because people buy new releases and they can make more money from the better-quality, hard binding.
