Plethora of Weblinks for the US in 20th Century World Wars

This is an amazing site put together by Fordham University. It is nicely broken into the typical parts of world history (absolutism, scientific revolution up to WWI, WWII, Cold War, post Cold War, etc.   It is a great resource for both US and world history teachers.  For example under World War I, there are links to life in the trenches, primary resources, lectures on the different causes of the war, Zimmerman Telegram, personal accounts, life after the war and I am just touching the surface on just one of the links.
