endpaper : The double leaves bound into a book at the front and rear after printing. One side is glued to the inner portion of the boards (the paste-down) and the other is left loose (free endpaper).

remainder mark : Usually an ink marking of some sort which indicates that the book was designated a remainder. In most cases, it can be found on the edges of the text block in the form of a marker stripe or a stamp of some sort.

shelfwear : Minor wear resulting from a book being place on, and taken from a bookshelf, especially along the bottom edge.
