Personal standard of Adolf Hitler: The personal standard of Adolf Hitler was designed after Reichspräsident Paul von Hindenburg died on 2 August 1934.  Adolf Hitler abolished the title "Reichspräsident" and in its place instituted the title of "Führer" which henceforth could only be used when referring to him personally.  Hindenburg used a personal standard consisting of a black eagle on a square gold background edged by a border of black, white and red bands.  Hitler decided on 19 August 1934 to adopt a personal standard for himself, which was called "Personal standard for Adolf Hitler as Leader and Chancellor of the German Nation".  As he was also Supreme Commander of the Armed Forces it was somewhat later known as "The personal standard for Adolf Hitler as Leader and Supreme Commander of the Armed Forces" (German: "Standarte des Führers und Obersten Befehlshabers der Wehrmacht").

Heim's version of the table talk was published in 1980 under the title "Adolf Hitler Monologe im Führerhauptquartier 1941-1944".  Heim's edition relied upon the original German notes, recorded by Heim from 5 July 1941 to mid March 1942, and August–September 1942.  According to German historian Clemens Vollnhals, from a "source-critical point of view, the most reliable version of the "Table Talk" remains Werner Jochmann's edition of 1980."
