A cover of pasteboard, with a gummed and stitched
binding strip, used to hold one or more pamphlets.
The quality of the board generally used for this
type of binder, which is used in many libraries as
a permanent binding, is such that it sooner or
later (and usually sooner) becomes highly
acidified, transferring its acidity to the first
and last leaves of the publication, thus
acidifying them, also.
