wedge shaped
A bound book that is thicker at the spine than at
the fore edge. The condition is caused by
excessive, uncompensated sewing swell,
compensation guards that are too thick for the
inserted material, excessive guarding of damaged
folds, or by guards made of paper that is too
thick. Such a condition may at times also be the
reverse. where the fore edge is thicker than the
spine, because of swelling of the paper, or an
improperly folded map, etc. In the latter case,
the fore edge swells but the spine, being fixed in
position, does not. (236 , 256 )
