* Flyleaf: This is a blank or decorated leaf at the beginning or end of a book. It's often used for the owner's name, a dedication, or other notes.
* Endpaper: This refers to the blank pages at the front and back of a book that attach the cover to the book block. They can be used for the flyleaf, but sometimes are used for other purposes like maps, illustrations, or advertising.
It's important to note that the term flyleaf is more specific to the blank page where the owner's name is written, while endpaper is a broader term for the entire blank page.
