Endsheet

An important part of a hardcover book. It’s the paper that connects the book block to the cover, located at the beginning and end of the book. It’s usually a single sheet folded in half, with one side, called pastedown glued to the cover and the other side stay free called the flyleaf, with its edge glued along the book block. Endsheets usually use thicker paper to help hold the book together and can sometimes feature a decorative design.
