Often used to denote a book that was published previously by a different publisher. The statement of how many copies were published often appears on the colophon page, and occasionally elsewhere. Often each copy of a limited edition will be numbered. Some limited editions are also signed by the author. Hard cover is self-explanatory.
Wrappers refers to a paper binding.
The terms soft cover, paperback, and wraps also refer to a paper binding. Mass market paperback is the format most popular novels are published in. The larger size paperbacks, often about 6 x 8 inches or so, are called trade paperbacks. Click here for a photographic size comparison of mass market and trade paperbacks. Signed means signed by the author, or occasionally by the editor or illustrator.
