Modular library system (compact disc housing unit)

A compact disc housing unit for storing CD's, musical or computer software in design, comprises:

• a main housing unit, an inner unit, six individual smaller units, two support members, and a turntable;
• wherein the main housing unit comprises of a lower plate, an upper plate, a pair of opposing side walls, a rear wall, an inner retractable plate, two support members, each of which is comprised of two pieces having annular projections along their edges which when fitted together enclosed one within the other, such that a multiple of steel balls housed within said annular projection allow for a sliding motion between said two pieces, wherein a larger enclosing piece of the support member is mounted securely to the inner side of the two opposing side walls, where the side walls meet the lower plate via a multiple of equally spaced intervals, wherein a smaller enclosed piece of the support member is secured by mounting means to the inner retractable plate via a multiple of apertures, where on top of the inner retractable plate is a bottom dish of a turntable, disposed with a central projecting post which when coupled with a hollow post of the upper dish of the turntable allows the inner unit full rotation, where the upper dish of the turntable is secured to the inner unit by mounting means, multiple short bosses disposed on the upper face of the bottom dish, the bottom face of the upper dish being formed with a corresponding annular groove wherein steel balls can be disposed within said annular groove permitting the inner unit to smoothly rotate relative to the bottom dish;
• the inner unit comprising a lower plate, an upper plate, a pair of opposing side walls, and two inner walls parallel to the opposing side walls;
• in addition, each of the six individual smaller units positioned three by three back to back within the inner unit are comprised of a lower plate, an upper plate, a rear wall, a pair of opposing side walls, and a drawer pull located on each individual smaller unit parallel to and equal distance from the lower plate and upper plate;
• the inner side of each of the opposing side walls of said individual smaller units having a plurality of spaced parallel elongated ribs formed on said inner side providing storage slots between adjacent pairs of the ribs for receiving CD's therebetween.
