Flattermarken

Flattermarken (a German plural; the singular is "flattermarke") are the marks used on the edge of printed material such as sections of books to facilitate their being arranged in the proper order. The symbology allows for the coding of any sequence of numbers through the position of bars. The bars themselves are of the same size and shape, but their position varies.
