lining paper; end leaves (of a book)
Refers to paper used for backing or lining, such as the endpapers of a book or the reinforcing paper in crafts and conservation.
The endpapers of this book are printed with a beautiful pattern.
For restoring hanging scrolls, we use thin lining paper.
Compound of 裏打ち (urauchi, 'backing, lining') + 紙 (kami, 'paper'). The exact historical derivation is uncertain, but the term is conventionally associated with paper used for reinforcement or finishing.
