Abstract: A holder (42) with retaining device for organizing compact disc cases and other such substantially rectangular media cases. The retaining device allows deposited items to be placed solitarily or adjacently in any available location, to be relocated simply by sliding them sideways, saves the vacant spaces left by withdrawn items, and will accommodate a variety of media case types, including compact disc cases of the single, multiple and slip-cased variety. A preferred embodiment of the holder has a substantially rectangular storage area (34) defined in part by opposed upper and lower shelves (36 & 40) located adjacent to an access opening (32) on the front side of the holder through which compact disc cases (50) and other such items are deposited in a side-by-side, book-like manner, coming to rest on and perpendicular to the interior surface of the lower shelf (40). The back wall (38) serves to stop deposited items from exiting out the rear side of the holder.
