To clarify, I am a high school social studies teacher trying to create a case study around the Panama Canal. This case study is part of a broader unit on how nations interact and why nations interact the way they do. Finding sources from the US perspective has been relatively easy, but I have been struggling to locate sources that are actually from Torrijos, Noriega, etc. If you want any further clarification, I'll be happy to provide it, but any direction on where to find sources would be very helpful. Thanks in advance!
While our users may be able to help you out here, 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.
