All editions and translations are based on the two original German notebooks, one by Henry Picker and another based on a more complete notebook by Martin Bormann (which is often called the "Bormann-Vermerke"). Henry Picker was the first to publish the table talk, doing so in 1951 in the original German. This was followed by the French translation in 1952 by François Genoud, a Swiss financier and a principal benefactor of the Nazi diaspora. The English edition came in 1953, which was translated by R. H. Stevens and Norman Cameron and published with an introduction by historian Hugh Trevor-Roper. Both the French and English translations were purportedly based on the "Bormann-Vermerke" manuscript while Picker's volume was based on his original notes as well as the notes he directly acquired from Heinrich Heim spanning from 5 July 1941 to March 1942. The original German content of the "Bormann-Vermerke" was not published until 1980 by historian Werner Jochmann. However Jochmann's edition is not complete as it lacks the 100 entries made by Picker between 12 March and 1 September 1942. Both Heim's and Picker's original manuscripts seem to have been lost and their whereabouts are unknown.
