Kommunist -- a magazine organised by Lenin. It was published in Geneva by the editors of the newspaper Sotsial-Demokrat in 1915. Only one issue (a double issue) appeared. It contained three articles by Lenin: "The Collapse of the Second International", "The Voice of an Honest French Socialist", and "Imperialism and Socialism in Italy" (see present edition, Vol. 21, pp. 205-59, 349-56, 357-66).
Lenin had planned to make Kommunist an international organ of the Left Social-Democrats. But the editors of Sotsial-Demokrat
soon became involved in serious disagreements with Bukharin, Pyatakov and Bosch, which grew worse after the magazine appeared. In view of this group's anti-Party conduct the editors of Sotsial-Demokrat, on Lenin's suggestion, announced that they considered it impossible to continue publishing the magazine.
Lieberdans -- ironic nickname for the Menshevik leaders, Lieber and Dan, and their supporters. It caught on after a satirical article by Demyan Bedny called "The Lieberdan" had appeared in the Moscow Bolshevik newspaper Sotsial-Demokrat No. 141, August 25 (September 7), 1917.
