Abstract: A series of add-on modular clips are serially hinged to one another to hold the disc containing cases in staggered position for storage. The face of any selected disc can be accessed for easy identification and disc retrieval by opening the cover of the selected disc case without removing the case from the clip. Each clip has a resilient unitary U-shaped member with legs of unequal width and of a shape for easy case insertion. A double clip member is also provided to hold two series of single clips, the clips of each series progressively more spaced to permit case opening of any selected disc of one stack of cases without interference from the other stack of cases.
