Abstract
Abstract An end sheet, which may be reinforced with fabric, paper or other material, is bound along with the pages of the book and the corresponding end sheet for the opposite end of the book by means of plastic strip retainers as disclosed in U.S. Pat. No. 3,730,560. The end sheet is secured to the inside of the cover of the case by adhesive. In preferred forms of the invention, at least one portion of the end sheet extends from under the spine edge of the plastic strip and folds outside the outer surface of the strip. In this form, the cover lies flat when opened. In other preferred forms, the end sheet extends from under the plastic strip in both directions.
