The title page of a book is a page with a complete title before the text of the book, which usually includes (but not necessarily includes) the author, edition, publication and other detailed information. The back of the title page usually contains information about edition, publishing, binding and copyright. Title page is the main information source of cataloging.

The title on the cover of a book is different from the title page. The title page is a page in a book, usually after the cover, which contains the official title and related information of the book. The cover of a book is the outer packaging of the book, which usually only contains the title, author's name and publishing company information.
