Abstract: A file card for use in a filing system for compact filing of information. Such a system includes a file receptacle for a plurality of the file cards. The cards include fulcrum means adjacent their bottom edges and are normally supported in the file receptacle in substantially vertical positions. However, by manually fanning apart any pair of the file cards at their top edges, the fulcrum means of these and adjacent cards cooperate with one another and with the file receptacle to automatically fan apart the upper portions of file cards adjacent the manually fanned apart cards, thereby making visually scannable the information on the upper portions of such cards. In one embodiment the file cards are merely divider cards, and data cards are inserted between them. In this instance the data cards are supported by a data card support arrangement which is integral with the file receptacle, and holding elements are provided on the file cards to position the data cards against desired ones of the file cards.
