The interior surfaces of a book’s protective casing serve several key purposes. These surfaces, typically paper adhered to the boards, often contain printed information or designs. For instance, they might feature author biographies, summaries, promotional material for other works, or decorative endpapers.
These surfaces contribute significantly to the overall aesthetic and functional value of the book. They provide a space for expanding upon the information presented, enhancing the reader’s engagement with the text. Historically, elaborate designs on these surfaces were considered a mark of quality and craftsmanship, signaling attention to detail in the book’s production.
