Front cover, spine, and back cover of the dust-jacket:
The front cover is the front of the book, and is marked appropriately, by text and/or graphics, in order to identify it as such, namely as the very beginning of the book. The front cover usually contains at least the title and/or author, with possibly an appropriate illustration.

The spine is the vertical edge of a book as it normally stands on a bookshelf. It is customary for it to have printed text on it. In texts published and/or printed in the United States, the spine text, when vertical, runs from the top to the bottom, such that it is right side up when the book is lying flat with the front cover on top. In books of Europe, vertical spine text traditionally runs from the bottom up, though this convention has been changing lately. The spine usually contains all, or some, of four (4) elements (besides decoration, if any), and in the following order: (1) author, editor, or compiler; (2) title; (3) publisher; and (4) publisher logo.

The back cover often contains biographical matter about the author or editor, and quotes from other sources praising the book.
