Abstract: An improved indexing apparatus with a wide range of uses which is intuitive to use, and economically manufactured using a minimum of materials and manufacturing steps. The preferred embodiment comprises a central index with an index portion and a marking portion printed on a layer of sheet stock with adhesive backing. Markers are die-cut from the same layer of sheet stock as the central index and have unique identifiers corresponding to unique identifiers on the marking portion of the central index. The markers and the central index are completely severed from each other and are held adjacent by their mutual releaseable attachment to a common backing sheet. A portion of the backing sheet is removable to allow attachment of the device to a document or other surface, the remaining portion serves to hold the markers adjacent to the central index.
