摘要： An arrangement for displaying study aids together with textbooks, in which a horizontal supporting plate is mounted on vertical supporting plates or struts. A plurality of textbooks are stacked on the horizontal plate and are relevant to a specific field of knowledge to be learned by students. A plurality of study aids are located beneath the horizontal plate and within a volume defined by the horizontal plate as well as the vertical struts. The study aids are visible simultaneously with the textbooks to an onlooker when removing a textbook from the stack resting on the horizontal plate.
