US Patent 7744128 Devices and methods for supporting printed matter

A book block is contemplated to be bound in its individual sections through various techniques. These sections will be attached to the book cover by a magnetic or mechanical way. The user of the book will then be allowed to select and detach individual sections of the book without destroying the integrity of the entire book block. Likewise, publishers of the book are now able to update and/or replace sections of an entire book block without needing to reprint and republish the whole book.
