This book is without question the most useful and comprehensive reference book on the Seond World War to appear in a single-volume, paperback format. It presents data ranging from amazing weapon specifications to wonderfully detailed biographies. Along with the many facts and dates of WWII, the book also includes information that while not common knowledge, is vital to a complete understanding of the conflict. For example, the book explains the strategies, theories, and the complex organization of the axis and allies. In addition, this wealth of information is presented in an easily accessible manner. While it can be read like a book, it is most useful as a quick reference. When I'm reading a book and come upon something I'm not familiar with, I just look in the Oxford Companion for a concise, yet complete explanation. It truly is a superb book.
