half extra
1. In craft bookbinding, "half extra" letterpress
binding is defined as any half-leather binding
forwarded in boards, regardless of any decoration
or lack of it. A half extra binding is one
usually, but not necessarily, sewn on raised

bands are usually used. 2. In stationery binding,
"half extra" is defined as a blankbook made up of
machine-made paper that has been tubsized. Four
sections are taped at front and back, and the book
is sewn on webbings. It has a SPRING-BACK (1) ,
made endpapers, cloth joints sewn on, leather
linings between the webbings, and is covered on
the spine and corners with calfskin or roan and on
the sides with paper. (152 , 236 )
