Abstract
A system for displaying audio content with text including a book holder and a book. The book holder identifies which book of a plurality is placed in the holder by detecting magnetic indicators in specific locations and arrangements which are unique to each book. The page of the book which a user views at any given time is identified by detection of ambient light, by detection of a number of circuit elements in parallel, by detection of progressively stacked magnetic sensors, or by microwave reflection.
