Father emptied a card le for Margot and me and lled it withindex cards that are blank on one side. This is to become ourreading le, in which Margot and I are supposed to note down thebooks we’ve read, the author and the date.
Anne Frank (June 12, 1929-1945)<br /> Niklas Luhmann (December 8, 1927-1998)
Niklas Luhmann was a year and a half older than Anne Frank who received her first card index file in February 1943 (likely between the 27th, the date of her diary entry mentioning it and the prior diary entry on February 5th), from her father at the age of 13. She was intended to use it as a "reading file" to note down the books she'd read along with the author and the date.
One can only wonder at how many entries she would have made over the span of her life had it not come to such an abrupt end.
