ABSTRACT:
This invention is directed to an information storage card having a vertical rear edge with a series of coded notches for identification and selection. When the card is carried in a pack of similar cards the rear vertical edge of each card is aligned so that the notch coded edge of each card is similarly positioned for selection. Accordingly, the selection means of an appropriate card sorting apparatus will be provided with code bars to engage the aligned vertical edges of the cards to distinguish certain selected cards from the remaining cards of the pack. A further notch is also provided in the top of each card which is defined by a vertically extending abutment edge intended to be engaged by means on the apparatus to prevent forward movement of that card. Yet, a further notch is positioned in the rear lower corner of the card at the bottom of the vertical rear edge and is defined by a downwardly facing horizontal edge extending from said vertical rear edge of the card inwardly and adapted to be engaged by additional means of the apparatus for raising the card in order to effect separation between the selected card and the remaining cards of the pack.
