Abstract: A book structure is disclosed that is much easier to use than books of conventional construction. It can be used by individuals with impaired motor function and by young children who have not yet developed sufficient coordination to manipulate the pages of a conventional book. Each leaf of the book is of a rigid plastic construction with projections above and below the plane of the leaf for holding printed matter on cards. The projections also serve as spacers to separate the pages from one another to facilitate grasping a selected page. Each page further has a rigid tab projection to serve as a handle. A binder assembly permanently holds the leaves for easy turning and to lie flat at any opened page. The binder includes a handle for easier carrying. The assembly is of a smooth, non-toxic plastic material that resists destruction by young children. The printed matter cards may be replaced with new editions as required without the expense of binding each edition, since the book assembly is reusable.
