half cloth
A book bound with a cloth spine, but not cloth
corners. The sides are generally paper, which is
also used for the spine title label. The style was
fairly common on publisher's bindings from the
late 1820s to the early 1840s. for three-volume
novels into the early 1850s, and occasionally for
general works since about 1890. The style was
correctly (though not often) called "quarter
cloth" by job binders. Also called at times "half
linen." (69 , 335 )
