Definition & Meaning of "endpaper"

What are "endpapers"?

Endpapers are the sheets of paper that are glued to the inside covers of a book, connecting the book's cover to the pages. They are typically found at both the beginning and end of a book. Endpapers can be plain or decorated and help to reinforce the binding by providing a sturdy connection between the cover and the text block. They may also feature designs or patterns that complement the book’s overall aesthetic.
