An instant book binding system and book cover for rapidly binding single- or double-sided documents, photographs, pages, and other forms of hardcopy media into soft or hard cover books is disclosed. The book binding method using the book cover or system can be performed without special skills or training, and does not require the use of ancillary equipment. The book cover system can be used in conjunction with output on a wide variety of media types, finishes, and stock weights from any type of printer or copier, or with photographs. The finished books retain the appearance and function of conventional mass produced soft and hard covered books.
