A rolling index card holder comprises a plurality of cradle-like sectors which include opposing faceted side walls extending from a core sector. The faceted side walls provide a means for supporting the holder and the sectors are hinged together so that the card holder may be opened to provide convenient access to all of the index cards within the device. Preferably, the holder is mounted from a standard plastic material with the hinges between adjacent sectors being formed of a thinner-gauge plastic.
