A notice sent to recipients of the Schriftenkartei: “With the 5th delivery you receive today, you have index cards with 527 typefaces. The type index is now complete for the time being. From now on, you will only receive the corresponding type sample index cards from the office of your responsible regional association for the newly created typefaces that are included in the casting program of the German type foundries.” In the end there were a total of 638 typeface cards, adding up to about 200 families.

The initial version of the Schriftenkartei had 527 typefaces (and thus cards), but with the release of subsequent typefaces it eventually grew to 638 typeface cards accounting for up to about 200 families.
