Improved lay-flat book products such as a book block ( 20 ) are provided which include a plurality of individual, marginally notched, alternating sheets ( 22, 24 ) having offset inner binding notches ( 30, 32 ); adhesive ( 36 ) is applied to essentially fill the notches ( 30, 32 ) in order to bind the sheets ( 22, 24 ) together. Preferably, tape ( 38 ) is applied to the spine surface ( 34 ) of the book block ( 20 ) and to adjacent portions of the outermost sheets thereof. Hard covers ( 48 ) and cloth binding ( 52 ) can also be added if desired. In a preferred method, a supply of marginally notched, unprinted A and B sheets ( 22, 24 ) are fabricated and the sheets may then be printed using digital equipment (e.g., programmable copiers) followed by adhesive binding. This permits economical production of short-run book products.
