ABSTRACT A library file of microfiche film comprises a plurality of spaced parallel film stored inside a cartridge. In a microfiche reader, a reciprocally moving extractor moves into and out of the cartridge to extract and return microfiche. An elevator selectively raises or lowers the cartridge relative to the extractor, thereby selecting a particular microfiche. Suitable interlocks prevent the elevator from moving after a microfiche is extracted and before it is returned to the cartridge.
