Abstract: A rotary die storage and retrieval unit, a rotary die storage rack, and a rotary die storage cart are disclosed. The unit is for an automated storage of a rotary die upon a rotary die shelf and for an automated retrieval of a rotary die from upon the rotary die shelf. The rotary die shelf is disposed within the rack, and accessible through a side opening of the rack. The rotary die shelf is either adjoined to the rack, or adjoined to the cart which is disposed within any embodiment of the rack capable of housing the cart. A frame of the unit is movably mountable to the rack. When the frame is movably mounted to the rack, the frame is operative to be aligned with the rotary die shelf. A carriage of the unit is movably mounted to the frame and is also operative to be aligned with the rotary die shelf.
