A responsive book system comprising: - a book comprising a plurality of detectable pages and a detecting system, for detecting a current page from the plurality of detectable pages of said book; - the book having a storage, for storing content associated with each of said detectable pages, the content of the plurality of detectable pages combining together to form a story of the book; characterized by: the detecting system including an array of magnetic sensors (36, 42) in the binding of the book, further characterized by two three-dimensional dolls, each of said two three-dimensional dolls having a receiver embedded therein and having a means for motionally playing the audio content associated with said current page, each three-dimensional doll positioned external to the book having an appearance conveying a suggestion of life; the detecting system of the book sensing changes in an electromagnetic field when said current page is turned by a user, so as to identify a particular page of the book as the current page, a magnitude of the electromagnetic field as the current page is turned being proportionate to a distance between (i) a magnetic sensor (36, 42) of the array, uniquely associated with the current page and located in the binding, and (ii) a first magnet situated in a distinctive zone on the cross-sectional area of said book, each distinctive zone associated with one of said plurality of detectable pages, the first magnet uniquely associated with said current page so as to identify a particular page of the book as the current page, the book having at least one transmitter configured to transmit to said dolls a plurality of signals providing information from the storage including a first signal to a first doll of the two dolls specifying the response of the first doll concerning said current page and including a separate and independent second signal to a second doll of the two dolls specifying the response of the second doll concerning said current page; and each of the one or more receivers configured to receive said separate first or second respective signal of the plurality of signals, wherein the responsive book system is configured to allow a user to turn current pages of the book and thereby hear the two three-dimensional dolls play the audio contents of the current pages by using the storage in the book as a single source external to the dolls, to simultaneously transmit a plurality of separate and independent signals of the plurality of signals respectively to each of the three-dimensional dolls wherein a content played by the first doll and a content played by the second doll are each determined from a content of the storage in the book, wherein each of said magnetic sensors (36, 42) comprises a resonance circuit in said distinctive zone in the binding, and for detecting the first magnet in said current page, wherein said detecting system further comprises at leas a second magnet (18a, 18b) located in said distinctive zone on at least one page (16a, 16b) between said first magnet and said resonance circuit, said second magnet (18a, 18b) for increasing the detectability of said first magnet. - a book comprising a plurality of detectable pages and a detecting system, for detecting a current page from the plurality of detectable pages of said book; - the book having a storage, for storing content associated with each of said detectable pages, the content of the plurality of detectable pages combining together to form a story of the book; two three-dimensional dolls, each of said two three-dimensional dolls having a receiver embedded therein and having a means for motionally playing the audio content associated with said current page, each three-dimensional doll positioned external to the book having an appearance conveying a suggestion of life; the detecting system of the book sensing changes in an electromagnetic field when said current page is turned by a user, so as to identify a particular page of the book as the current page, a magnitude of the electromagnetic field as the current page is turned being proportionate to a distance between (i) a magnetic sensor (36, 42) of the array, uniquely associated with the current page and located in the binding, and (ii) a first magnet situated in a distinctive zone on the cross-sectional area of said book, each distinctive zone associated with one of said plurality of detectable pages, the first magnet uniquely associated with said current page so as to identify a particular page of the book as the current page, the book having at least one transmitter configured to transmit to said dolls a plurality of signals providing information from the storage including a first signal to a first doll of the two dolls specifying the response of the first doll concerning said current page and including a separate and independent second signal to a second doll of the two dolls specifying the response of the second doll concerning said current page; and each of the one or more receivers configured to receive said separate first or second respective signal of the plurality of signals,
