Abstract
An assembly for housing microfilm is provided. The assembly includes a first cartridge, a second cartridge, and a connector assembly for detachably connecting the first cartridge to the second cartridge along an offset axis of the assembly. The first and second cartridges have a base plate and a cover plate secured together by a second connector assembly. The first connector assembly pivotally connects the two base plates together at a pivot point to allow each of the cartridges to rotate about the offset axis. The offset axis extends through the pivot point and is perpendicular to the plane formed by the junction of the first cartridge and the second cartridge.
