ABSTRACT An improved rainshed binder is disclosed for protect- ing a book from environmental weather conditions. The binder has first and second covers each of which have rainshed protecting walls connected to inside surface side edges of the covers. An integral binder backbone connects the first and second covers. The backbone has a pair of linear polyethylene hinges positioned inwardly of outer rigid, non-flexible corners of the backbone. The backbone connects in integral manner with the first and second covers at the rigid corners. An attachment plate secures the book to be protected to the backbone between the flexible hinges. The rigid corners of the backbone are free to flex relative to the book attachment plate by the provision of the hinges. The binder is designed to hand downwardly in closed fashion when the book is not in use. By providing the hinges inwardly of the rigid corners of the backbone, a center of gravity of each of the covers and connected rainshed protecting walls is laterally outwardly of the hinges so as to create an in- wardly directed force for each of the covers so as to cause the rainshed protecting walls to overlap one another in a closed fashion.
