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."

The first political piece by Hitler, it is thought to have established his credentials as a radical rightist and, amongst conservative groups, as the man who could overthrow the Weimar republic.  Because the letter is the first record of Hitler's antisemitic views, and because it brought Hitler into politics, it is considered an important document in Holocaust studies.

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".
