Half Bound: A book in which the spine and corners are bound in
a different material (usually a better material such as leather) than the remainder of the boards which can
be covered with plain paper, marbled paper, or cloth. Although infrequently found, there are half-bindings
with foreedge trim in which the spine and the right edge of the cover(s) are trimmed with the center portion
covered in cloth or paper. See Figure 15.
Half-Title: A page which usually precedes the full title page
bearing only the title of the book, or sometimes an abbreviated title if the full title is rather long.
Headband: A narrow cloth band, sometimes colored or multi-colored,
appearing inside the top and/or bottom of the spine cover. Originally, during the hand-sewn period, it was
intended to add strength. Since the advent of machine sewing, the presence of such bands is imitative and
decorative. See Figure 16.
Head(s)/Headpiece: A decorative device or motif consisting of a
small illustration or ornament found at the start of each chapter or other divisions within a book. Often,
but not always, a motif is repeated with or without slight variations with each use.
Hinge: The flexible channel where the paste-down endpaper
meets the free endpaper is the visually evident location of a hinge in an intact book. The entirety of
the hinge, in both hand and machine bound books, is concealed behind the endpapers. For example, as discussed
in the above entry for a Case Bound book,
the hinges of a machine bound book include the gauze extensions glued over the spine and onto both covers.
Thus, most descriptions of defective hinges implicitly reference more than the channel.
See Shaken. The term is often used incorrectly as interchangeable with the term Joint,
the proper name of the flexible groove where the cover Panels of a books meet the spine cover.
See Figure 5.
