Hurried by the Central Authority of the Communist League which provided him with certain documents (e.g., addresses of the People’s Chamber (Halle) of the League of the Just of November 1846 and February 1847, and, apparently, documents of the First Congress of the Communist League pertaining to the discussion of the Party programme), Marx worked intensively on the Manifesto through almost the whole of January 1848. At the end of January the manuscript was sent on to London to be printed in the German Workers’ Educational Society’s print shop owned by a German emigrant J. E. Burghard, a member of the Communist League. The manuscript of the Manifesto has not survived. The only extant materials written in Marx’s hand are a draft plan for Section III, showing his efforts to improve the structure of the Manifesto, and a page of a rough copy. The Manifesto came off the press at the end of February 1848. On February 29, the Educational Society decided to cover all the printing expenses.
