When _more_ than one section, sometimes called signature, is loose in a
book which is worth rebinding, it should be rebound at once.
When the thread in one section only is broken, or one section only is
loose in a rebound book and the rest of the binding is intact, the
section should be inserted. To avoid further ravelling, it is necessary
to secure the broken threads of the book either by fastening them
together, or attaching to new threads; also that the loose section is
sewed or tied through the super on the back of the book.
LOOSE SECTIONS may be inserted as follows:
If the folds of the leaves in the loose section are torn or thin,
they should be mended before replacing the section. Take a half-inch
strip of thin, firm paper, the length of the page; fold through the
middle lengthwise and paste down through the center fold of the
leaves. A touch of paste along the fold of each will hold all the
sheets together.
Open the book at the place where the section is loose.
(When the book is open the back of the book separates from the
cover.)
Open the loose section and place it in the proper position in the
book. Near the top and bottom in the center fold of the section will
be seen the holes which were made by the binder.
Thread a needle with Barbour's linen thread No. 40, or Hayes' linen
thread No. 25, and tie new thread to broken end of thread in book.
Pass the needle through the hole at the top of the loose section and
out between the book and its loose back. Do not pull the thread
clear through.
Drop the needle and thread down between the back of the book and the
loose back to the bottom.
Run the needle and thread from the outside in through the hole at
the bottom of the loose section.
Pass the needle and thread around again in the same way. Draw tight
and tie with a hard knot at the point of beginning.
