Offering a comprehensive account of the war as more than a purely military phenomenon, World War I: A History in Documents, Second Edition, also addresses its profound social, cultural, and economic implications. Authors Marilyn Shevin-Coetzee and Frans Coetzee use editorials, memoirs, newspaper articles, poems, and letters to re-create the many facets of the war. Technological developments such as the machine gun and barbed wire brought the world trenchwarfare, which is vividly depicted here in a firsthand account of then-soldier Benito Mussolini. An Atlantic Monthly essay by the African-American sociologist W.E.B. Du Bois draws attention to the conflict's origins in imperialist greed in Africa.
