ABSTRACT:
A booklet suitable for use as a testbook or as a supplement to other printed publications is made from a single continuous web of paper which has printed matter on both sides thereof, and which has been folded alternately in opposite directions along successive perforated lines extending transversely of the web at a constant longitudinal spacing. The folded web is stapled or otherwise held together along a rear binding edge. The thus produced booklet has every two neighboring leaves thereof joined together at their unbound edges opposite the binding edge. Such joined leaves are to be separated by the reader by tearing the same along the row of perforations between at their unbound edges. The top and bottom edges of every two neighboring leaves extending between the binding and unbound edges may further be sealed together in a readily openable manner. In the use of this booklet as a testbook, for example, questions and answers may be printed on the outer and inner pages, respectively, of every two joined leaves.
