Abstract

A microfilm card adapted to be used with a microfilm reading device. The card has an image area having a plurality of images arranged in rows and columns, at least one of the images containing an expanded index of the location of the images. An index area adjacent to the image area contains a plurality of indexes thereon, with the index area precisely and accurately positioned with respect to the image area. The indexes relate to their respective expanded index on the image area, the index viewable directly by the operator. There are means on the microfilm reader which interface with the microfilm card to position the card in the reader in the same precise location each time it is to be viewed.
