ABSTRACT:
A pocket containing business form is formed from an intermediate which comprises a sheet of paperlike material having dimensions of about 8.times.11 inches. The sheet is guillotine cut in two lengthwise, and each of the sections is eccentrically Z-folded to form a pocket, with pressure activated adhesive strips sealed along the edges of the pocket. The portion of the sheet exposed above the pocket is imaged by a laser printer, etc., for example, to indicate due dates for library books. The form is glued on one of the inside covers of a library book, and a 3.times.5 card containing information about the book is inserted in the pocket.
