Abstract: A sound-illustrated, bound book includes sound record areas in the form of a spiral sound groove each associated with individual pages. Adjustment perforations or embossments or engravements and switch-on safety elements, if provided, for a sound reproducing apparatus attachable in aligned position, are associated with each sound groove. It is suggested to provide the sound grooves with the adjustment perforations and the switch-on safety elements on separate double pages of plastic material, at best being semi-rigid, and bound in the book, inserted into the quaternia thereof, in order to permit more favorable production of the individual book pages and of the sound groove carriers and to prevent any obstruction when the book is read with a sound reproducing apparatus having a revolving pickup placed on the sound groove and to avoid too much bulging of the book, especially toward one side.

Abstract: Apparatus for teaching reading comprises a book having lines of printed text and recordings of the text on associated magnetic strips and a pick-up member of sufficient weight to rest securely on the magnetic strips is provided with a tension member by which the pick-up member may be drawn manually or by a spring motor along the magnetic strips. The pick-up member may be shaped in a manner designed to appeal to the imagination of a user, for example as an animal.
