A statement to the effect that advertisements have
been included in the binding of a volume bound
from parts or issues, or in the rebinding of a
volume, usually a serial publication. Some
libraries instruct the binder to remove all
advertisements not containing subject matter (on
either side of the leaf), or those that are
paginated separately. This is done to save shelf
space; it is questionable, however, whether
sufficient space is saved to warrant the effort.
In addition, the presence of advertisements can be
of value to scholars and is of value to collectors.
