Although each commented text and letter volume of the twenty-one-volume complete edition of Tucholsky is provided with a detailed appendix, there is a comprehensive index at the end, which can best be understood as a reference work for Tucholsky's texts. Those who wish to trace Tucholsky's themes over the years can locate the relevant passages in the texts using the keyword index. For example, under "antisemitism," one can find out how many references there are in addition to a central article on the topic. In addition to the factual keyword index, which includes places, institutions, parties, organizations, and publishers, the volume contains a person and work index, an index of books, theater, and film performances discussed by Tucholsky, as well as lists of text and poem titles, letter recipients, and the contents of the collected volumes.
