Social Science Homework Help

My current course is International Law, and I am struggling to find informative resources online about the

subject, and I don’t know if it is keywords that I enter, either being the wrong ones, or if my search engine input is too wordy. Is there a website that I may not be aware of? I find samples on here of the assignments that I work on, and they seem to find great information when I come up dry. I don’t know what I am entering or not entering into the search engine to find the info I need. Any suggestions?
