The book is gripped by a book holder ( 35 ) proximate the spine (S) of the book and the book holder is vertically positioned such the shear blade will shear the book in a predetermined position along this first edge of the book. The book holder is then moved transversely with respect to the blade and the book is rotated 180° and the book holder is vertically positioned so that a predetermined amount of the margin along this second edge is trimmed from the book upon closing of the shear blade. The book is then moved transversely to a third position and the book is rotated 90° and the book holder is vertically positioned so that a predetermined amount of the margin along this third edge is trimmed from the book upon closing of the shear blade.
