guarded endpaper
A section which has had a linen GUARD (1) wrapped
around both it and the endpaper so as to
effectively make one unit of the two. Its purpose
is to provide additional strength at the point
where greatest flexing occurs, which is between
the endpaper and the first leaf of the section.
The guard is usually attached so that not more
than 3/16 inch of the linen appears on the exposed
leaf of the section, while generally 1 1/4 inches
in on the unexposed side of the endpaper. In a
case binding the guard is tipped to both the
section and the endpaper, but in a handbound book,
because both section and endpaper are sewn
(through the linen), the guard is tipped only to
the section. In case binding the guard also
eliminates the necessity of tipping the endpaper
to the first leaf of the section and thus
eliminates drag on the leaf. In a hand-bound book
(where the endpaper is not tipped to the section)
one guard strengthens the folds of both the
endpaper and section; were two guards to be used
instead of the one, the guard would appear on the
first printed page of the book.
