A system providing efficient cataloging and storage of data-storage devices. The system comprises a plurality of removable holders adapted to hold at least one of the data-medium-containing articles. Each holder is adjustably mounted within a support comprising three cylindrically shaped members. While engaged within the support, the holders are free to move independently along the cylindrically shaped members to permit holders to be added or removed from any position within the indexed plurality of stored holders. The system is modular and may be expanded in size and capacity. The system may be integrated within furnishings.
