Abstract
In a hand-held digital data reader which functions as an electronic book, a hinged housing for two displays and display controls opens and closes in the manner of a printed book. In the open position, the two displays are presented as facing pages of a book. Each display is mounted between a rounded spine end emulating the rounded page surface of an open printed book, and a tapered thumb pad emulating the tapered page ends of an open book. Thumb operated display controls are on the thumb pads. The hinge has a traveling pivot point for maintaining contact between the surfaces of the two spine ends when the book is opened and closed.
