Methods and apparatus of integrating multimedia materials with didactic printed materials (25) present selected relevant multimedia material in response to the sensing of control codes (29A, 29B) embedded in context sensitive and/or content sensitive didactic printed material (25). A store (31, 51) of multimedia information is created, and the store (31, 51) is correlated to related context and/or content sensitive didactic printed material (25). The store (31, 51) is categorized to transmit certain categories (35, 37, 39, 49A, 49B, 49C, 49D) of the stored information from the store (31, 51) to a multimedia display (41) in response to the reception of certain input signals obtained from certain codes (29A, 29B) embedded in the didactic printed material (25). The printed didactic material (25) controls the display of multimedia material. Either preexisting didactic printed material or currently created didactic printed material can be efficiently and economically integrated with multimedia materials to display certain selected multimedia materials at sensitive places of the printed materials (25).
