Right now I am doing a project about after the Conclusion of World War I, when United States became a prominate world power compared to many European nations. I know that the United States economy was becoming the leading economy, especially with the debts that Europeans had accumulated topped with the pysical damage done to the territory. What am I am asking for you fellow CFCers if you have any good websites that further explains the United States as a rising power, and graphs and statistics comparing the United States economy and European economies during this time. I am limited to studing the 1920s only.

Some things I am having trouble finding are US currency to European currency during this time and national debts for both the axis and allies, so if you guys have any links, it would be greatly appriciated.
