The bookbinding system in question is a book cover with extended sides (flaps). The tough part of the book has two parallelogram-shaped portions and the soft one two velcro bands and a special sticky substance. It has the exterior appearance of a book and, due to the system of movable sheets and the facility of its back to get wider or narrow as the case may be, it combines the mechanical perfection and functionality of a book. It can be easily and economically manufactured, it has ergonomic and ecological properties, and it is resistant to exterior damaging effects.
