Only a small proportion of the card index of the Reichsvereinigung has survived. And another name went into the all-embracing card index. Gottfried van Swieten also successfully introduced the card index. There was also a personality card index which contained detailed information of people of interest. A card index alone was not sufficient to document all the frequencies. In 2017, the ITS has published the card index in its online archive. Jacobi maintained an extensive card index of Palaeolithic and Mesolithic sites, collections, and artefacts.
