Abstract
Abstract A handy bookbinder comprises at least one cover and a spine member. The spine member is formed with an adhesive face at one surface thereof. The spine member may or may not be attached to the cover at one side portion of its adhesive face. In the case where the spine member is attached to the cover, for use, sheets of paper to be held together are placed on the cover, and the spine member is bent and attached to one side of the whole of the sheets, and is attached to the uppermost sheet. Thus, the sheets are held together very easily as if a book were bound. If it is desired to add a new sheet or sheets to the book or to remove one or more of the existing sheets, the spine member may be stripped from the cover or the last sheet and the foregoing one side of the whole of the sheets. After the desired addition or removal, the book can be rebound in the same manner as described above.
