LEATHER - QUARTER LEATHER / QUARTER BOUND

Quarter leather (1/4), or quarter bound, describes books bound in leather at the spine, with boards covered in paper, cloth, or other material. Typically, the leather is narrow, covering the spine and no more than one-eighth the width of the boards.

The usage is subjective, and the term is used by some to describe what others term a LEATHER - HALF LEATHER / HALF BOUND binding without leather corners.
