Query: Great book, well written and reasearched.

"The Crisis of the Old Order" is well written and researched. It captures the times and era of great depression and the stock market crash of 1929, so vivdly that no other book on the subject can compare to it. This book is definetly worth buying and reading, also check out the other two volumes of the trilogy, "The Coming of the New Deal" and "The Politics of Upheaval."
