4. What follows is the compilation of the basic catalog; that is, all book titles are copied on a piece of paper (whose pagina aversa must remain blank) according to a specifi c order, so that together with the title of every book and the name of the author, the place, year, and format of the printing, the volume, and the place of the same in the library is marked.
Benedictine abbot Franz Stephan Rautenstrauch (1734 – 1785) in creating the Catalogo Topographico for the Vienna University Library created a nine point instruction set for cataloging, describing, and ordering books which included using paper slips.
Interesting to note that the admonishment to leave the backs of the slips (pagina aversa), in the 1780's seems to make its way into 20th century practice by Luhmann and others.
