The first edition of the Manifesto was a 23-page pamphlet in a dark green cover. In April-May 1848 another edition was put out. The text took up 30 pages, some misprints of the first edition were corrected, and the punctuation improved. Subsequently this text was used by Marx and Engels as a basis for later authorised editions. Between March and July 1848 the Manifesto was printed in the Deutsche Londoner Zeitung, a democratic newspaper of the German emigrants. Already that same year numerous efforts were made to publish the Manifesto in other European languages. A Danish, a Polish (in Paris) and a Swedish (under a different title: “The Voice of Communism. Declaration of the Communist Party”) editions appeared in 1848. The translations into French, Italian and Spanish made at that time remained unpublished. In April 1848, Engels, then in Barmen, was translating the Manifesto into English, but he managed to translate only half of it, and the first English translation, made by Helen Macfarlane, was not published until two years later, between June and November 1850, in the Chartist journal The Red Republican. Its editor, Julian Harney, named the authors for the first time in the introduction to this publication. All earlier and many subsequent editions of the Manifesto were anonymous.
