ABSTRACT:
A multi-channel transparent jacket having top and bottom panels joined by ribs to define parallel channels loadable with microfilm strips to create a reproducible microfiche master, the jacket having entry slots adjacent the front end of the channels to facilitate insertion of the strips. The lowermost channel is pre-loaded with a removable dummy strip to stiffen or somewhat thicken this channel and thereby prevent a partially-loaded jacket from buckling or sliding under when a stack of jackets is stored in a file drawer. The ends of the dummy strip are notched to facilitate the later loading of the lowermost channel through the channel entry slot with a film strip which displaces the dummy strip.
