I read this book to learn more about WWI; a reader more familiar with the war or with weaponry would probably rate the book much higher.
Each object is featured in a large (mostly full page) photo at the start of two or three pages explaining the item's significance. In general, the items offer a chronological view of the war. The exceptions are two sections at the end, "War at Sea, in the Air" (focusing, of course, on naval and air forces) and "At Home" (including prosthetic limbs and war memorials).
Archduke Franz Ferdinand's vehicle in Sarajevo, a 1911 Graff and Stift Double Phaeton, - now in a Vienna museum - is the first item. That's fitting, since his assassination triggered the war. The article that follows the photo describes the political situation in Austria-Hungary and its neighbors, as well as the details of the archduke's death.
Each object provides a link to a greater aspect of the war. The insignia from an ANZAC (Australia - New Zealand Army Corps) uniform leads to information about enlistment enthusiasm in those countries as well as ANZAC bravery at Gallipoli.
The objects represent mainly the UK, France, Austria-Hungary, and Germany, with a few Italian, Russian, and American items. American contributions to WWI are not at all well developed.
I learned a lot!!
I knew that on the western front, WWI was fought primarily from trenches. I did not realize that, in addition to long range artillery and grenades, troops frequently battled face-to-face with knives and clubs.
I knew that armies often use non-combatants in rear areas to serve the combatants, but I had no idea that the French and British hired over 94,000 Chinese laborers to work in ports, maintain vehicles, and build roads or airstrips. The British also employed men from South Africa, the West Indies, Egypt, India, and Fiji.
I'll admit that I skimmed some articles about weapons - because I don't know enough about gauges of metal or mechanisms to appreciate the information.
This book needed
1. a map of Europe. I know where the countries are; I'd like to understand where the battle occurred.
2. better editing. The frequent dangling modifiers made me crazy!
