I don't know if this is the right place to ask, but I need legitimate and helpful sites to find primary source documents for a project. I'm the only one I my team working on it seriously, and I'm struggling to find sufficient documents. Help? If you need more, I'm primarily looking for 1914-1942 documents about U.S. Foreign policy.
That is absolutely a fine question to post here. In addition to what our users may be able to help with, we hope that you also will take the time to check out our six-part series, "Finding and Understanding Sources", which should hopefully prove to be helpful for you as you continue in your research.
The one that I frequently use for the classes that I teach is: Fordham University's Sourcebook. That site is amazing.
Also, the Library of Congress has wonderful sources and resources. Check out their site, it's a bit overwhelming with how much they have.
