Our fourth series, World War (W.W.), arranged chronologically, contains correspondence, reports, and newspaper clippings dealing with many facets of United States participation in World War 1. Numerous letters are from relatives, friends, and acquaintances, requesting Brandeis's help in obtaining a military commission or a home front occupation. There are reports defining the problems of transportation, labor, taxation, and agriculture relative to the war effort; a daily digest of news items pertaining to the war effort as found in trade, labor and general papers; and correspondence and reports on the political and military situation in Russia. Of special interest is a translation of an article from Pravda dated April 28, 1918, of a piece by N. Lenin entitled "The Urgent Problems of the Soviet Rule."
