What does endpaper mean?
An endpaper is the sheet of paper — frequently decorative, marbled, or patterned — that is pasted down against the inside of a book's front and back covers, serving the practical function of attaching the sewn text block to its binding. Though largely hidden from view when a book sits closed on a shelf, endpapers are among the first things a reader sees upon opening a volume, and binders have long treated them as an opportunity for visual flourish, using hand-marbled papers in fine bindings. In bibliographic and antiquarian circles, endpapers carry real significance: their style, watermarks, and condition can reveal whether a book retains its original binding or has been rebound, which directly affects its value to collectors. Because most books have endpapers at both the front and back, the plural "endpapers" is the more commonly encountered form. The word belongs chiefly to the vocabulary of bookbinding, publishing, and book collecting rather than casual conversation.
nounA sheet of paper, often decorative or marbled, glued to the inside of a book's cover at the front and back to attach the text block to its binding.
- A sheet of paper, often decorative, pasted inside the front and back covers of a book to fasten the text block to its binding.
"The rare first edition still retained its original marbled endpapers."
"The binder chose a richly marbled endpaper to complement the leather spine."
"Collectors often check the endpapers for signs of rebinding before buying an antiquarian volume."
The plural is standard and often preferred, since books conventionally have endpapers at both the front and back; the singular refers to one such sheet.
"Both volumes featured matching floral endpapers chosen by the original binder."
Open any hardcover book and the very first thing you touch isn't the story — it's the endpaper, the humble sheet holding the whole book together.

Etymology of endpaper
The word "endpaper" is a straightforward English compound formed from "end" (Old English "ende") and "paper," which entered English via Anglo-Norman from Latin "papyrus." It arose as a term of the bookbinding trade, describing the sheets placed at each end of the bound text block. Its components are transparent, so it has no distant cognates beyond the many other English words built on "paper," such as "wallpaper," "newspaper," and "papier-mâché."
How endpaper is actually used
"Endpaper" is primarily used in bookbinding, publishing, and bibliographic contexts; it is a technical rather than everyday word. The plural "endpapers" is common because books have them at both front and back.
