ABSTRACT:
The invention is a foldable pull-out, index card for use with business file card systems that typically use two rails in order to hold a series of business type cards in a file. The pull-out, index card may be used with a set of business cards as an index or table of contents for the rest of the cards in the file. The pull-out card has a front panel with two notched portions in the bottom edge to guide the card along the pair of rails in the business card file. A series of intermediate panels fold out above the front panel and contain printed information pertinent to the subject matter of other cards in the file. The back panel of the card may also have a pair of notched portions to further secure the fold-out card in the file.
