A printed illustrated text, printed alphabetical text and printed illustrated index are all correlated to a set of recordings intended for audio visual display and which are in turn topically arranged. In addition the illustrated index may by themselves be recorded in their entireties for audio visual display. The illustrated text is presented by a main written portion heavily pictorialized by a key illustration and ancillary illustrations arranged in a predetermined sequence with ancillary supporting information. A conspicuously displaying cross-reference listing refers to other pertinent illustrated texts and topical audio visual recordings. The alphabetical text is correlated to pertinent portions of the illustrated text by having, on pertinent pages thereof, key illustrations from the illustrated text. It, in addition, carries cross-references to pertinent optical audio visual recordings as well as to other pertinent information in the system. The illustrated index, which may include reduced reproductions of entire pages from the illustrated text, is also cross-referenced to pertinent topical audio visual recordings. The jackets for each topical audio visual recording include a printed display of pertinent portions of the illustrated text and pertinent portions from the alphabetical text. In addition sub-topic titles, and/or illustrations indicative of such sub-topics, are arranged in positions corresponding to the position of the recorded sub-topic information; and are printed either directly upon the audio visual recording or a transparent sleeve carried by the jacket.
