The United States emerged from WWI as the world’s greatest single economic power.

Offering exhaustive coverage, detailed analyses, and the latest historical interpretations of events, this expansive, five-volume encyclopedia is the most comprehensive and detailed reference source on the First World War available today.

One hundred years after the beginning of World War I in 1914, this conflict still stands as perhaps the most important event of the 20th century. World War I toppled all of the existing empires at the time, transformed the Middle East, and vaulted the United States to becoming the world’s leading economic power. Its effects were profound and lasting—and included outcomes that led to World War II. This multivolume encyclopedia provides a wide-ranging examination of World War I that covers all of the important battles; key individuals, both civilian and military; weapons and technologies; and diplomatic, social, political, cultural, military, and economic developments.

Suitable as a reference tool for high school and undergraduate students as well as faculty members and graduate-level researchers, World War I: The Definitive Encyclopedia and Document Collection offers accessible, in-depth information and up-to-date analyses in a format that lends itself to quick and easy use. The set comprises alphabetically arranged, cross-referenced entries accompanied by further reading selections as well as a comprehensive bibliography. A fifth volume provides chronologically arranged documents and an A–Z index.

2015 Editors' Choice Selection—Booklist, November 20, 2014


"[T]his extensive examination of the war fulfills the aim of being a 'definitive' set. . . . The entries, overall, are succinct and well written. . . . This exhaustive encyclopedia is highly recommended for public and academic libraries where budget allows—particularly those without Tucker’s earlier incarnation of this set, The Encyclopedia of World War I: A Political, Social, and Military History (2006)."—Booklist, December 15, 2014
