Abstract: A hardcover binder that can be interchanged with a variety of binding mechanisms. A binding mechanism is removably mounted in the binder hardcover allowing for removal of the binding mechanism for recycling or replacement of the binding mechanism or binder hardcover. The hardcover has a pair of interior pockets that are offset from and open towards the hardcover's spine. The invention comes with a pair of inserts that can be perforated and integrated with binding mechanisms such as plastic comb or spiral. In the case of a 3-ring binding mechanism, the inserts can be affixed to the binding mechanism or the binding mechanism can be mounted on a single section of insert material resulting in two insert flaps that function the same as the inserts. The inserts (or flaps) are removably inserted and fit snugly into the interior pockets to anchor the binding mechanism against the spine and between the hardcover.
