Each of the 22 country sections provides detailed background information, the reasons behind the country's entry into the war, a summary of its combat effort in the war, a discussion of the home front experience, and a description of the war's impact on that nation. Illuminating sidebars offer an interesting war anecdote involving each country, while essays survey each country's military branches and key military and political leaders. Finally, a timeline for each nation covers all of the important events involving that country during World War I.
In addition to the country coverage, a battles section offers entries on 18 of World War I's most important engagements and a separate section on weapons and tactical changes is included.
