Abstract
A plastic microfiche carrier has a central clearance for enabling an insertion of a replaceable microfiche film in the carrier. The corners of the carrier are tapered to facilitate an alignment of the carrier, and therefore the microfiche in a library file housed within the cartridge. The front or leading edge of the carrier is concave in the width dimension with a bullet-like nose double taper in the thickness dimension to guide and direct the microfiche, as it slips into and out of the library file.
