Abstract: A bookbinding system shapes a booklet in such a manner that a paper sheet bundle composed of plural text paper sheets is bound by case binding using a cover paper sheet. In this case, a paper sheet having a size fitting within a region configured with a front surface, a back surface, and a spine of the paper sheet bundle is used as the cover paper sheet. For example, vertically-long A4 paper sheets are used as the text paper sheets, and a horizontally-long A3 paper sheet is used as the cover paper sheet to carry out case bookbinding. The cover paper sheet does not protrude from the outer shape of the paper sheet bundle. Thus, it is not necessary to cut the cover paper sheet, and no cutting waste is generated.
