  The Contributions was written between 1936 and 1938. Intriguingly, Heidegger asked for the work not to appear in print until after the publication of all his lecture courses, and although his demand wasn't quite heeded by the editors of his collected works, the Contributions was not published in German until 1989 and not in English until 1999. To court a perhaps overly dramatic telling of Heideggerian history, if one puts a lot of weight on Heidegger's view of when the Contributions should have been published, one might conceivably think of those later writings that, in terms of when they were produced, followed the Contributions as something like the training material needed to understand the earlier work (see e.g., Polt 1999 140). In any case, during his lifetime, Heidegger showed the Contributions to no more than a few close colleagues. The excitement with which the eventual publication of the text was greeted by Heidegger's readers was partly down to the fact that one of the chosen few granted a sneak preview was the influential interpreter of Heidegger, Otto Pöggeler, who then proceeded to give it some rather extraordinary advance publicity, describing it as the work in which Heidegger's genuine and complete thinking is captured (see e.g., Pöggeler 1963/1987).
