Extra-large and large hardcover books include a paper dust jacket that can hold text and photos. Besides having front and back covers that you can customize, dust jackets also have inside flaps that tuck behind the front and back covers.
You can customize these flaps, too. In publishing, it’s common for the front flap to describe the book, and for the back flap to describe the author. If there’s a lot to say about the book or its subject, the text on the front flap may continue on the back flap.
Each book theme has several flap layouts: just a photo, text and a photo, just text, and blank. When creating a hardcover book, decide how much you want to talk about your book—and yourself—and choose the appropriate layout.
