I bought this book because I was hoping for more of a overview of WWI. I've read a lot about WWII and always have found it useful to read something general first, then identify the elements you found really intersting and go buy a focused book on those aspects.
This is not really a beginers overview at all. It is a collection of writings by some apparantly well qualified scholars. Some parts are still very interesting from a beginers point of view, but the fact that it isn't really chronological is a little annoying. There is a chapter on the Central Powers strategy, a chapter on the war on the western front, a chapter on the effect on women, a chapter on the economic impact of the war, etc.
I think it is probably a really good book, it is just a tad advanced for a beginner like me. I probably should have paid more attention before buying it.
One other minor complaint is that that although the book has a ton of pictures (which is good), the captions are not great. For example, there will be a picture of 8 people standing there and the caption will tell you that one is an Italian general, who is talking to his king, but it won't tell you who is who (e.g. the King is the 3rd from the left). You just kinda have to guess who is who based on how old/important they look.
