Abstract: A portable index card holder is designed for carrying in notebooks or simply carrying by itself. The holder comprises a flexible member approximately the size of a notebook page having secured to its front surface a plurality of transparent sheets in an overlapping array between the top and bottom of the supporting member. These transparent sheets each includes small strip overlays defining front and rear pockets for receiving and supporting the lower marginal edge of an index card in such a manner that any one card can easily be inspected by simply lifting up the sheets above the same. The transparent feature permits reading both the front and rear sides of an index card without having to remove the same from the transparent sheet and holding member. Further, several such members can readily be inserted in a notebook such as a 3-ring binder for organizing many different cards in conjunction with other items.
