Abstract: The invention discloses a system for the organized storage of a large number of sheet- or disk-like record carriers, particularly of diskettes or microfiches. A container for holding the record carriers has a printed form that has line markings corresponding to a number of record carriers which have additional line markings on their outside edges. The line markings located on the edge of the record carrier are aligned with matching line markings on a printed form on the container. Several containers can be stacked or arranged side-by-side by attachments on the outside surfaces of the containers in order to combine the system simply and easily with other systems of this type into appropriate blocks. A locking plate also can be provided.
