A complete Marx-Engels edition depended on the SPD’s Berlin archive holdings

Evidence

Since the posthumous papers of Marx and Engels are held by the archive of the German Social Democratic Party in Berlin, and a complete edition of their works is not possible without using these papers exhaustively, the first phase of the work will be carried out there … Photographic copying will be carried out for the most part by the Institute of Social Research in Frankfurt am Main, with the greatest possible care and with a complete record of all peculiarities and special characteristics of the originals which cannot be recorded by photography. — Rolf Wiggershaus, The Frankfurt School, 119
