Hopefully, by now, you would have found many potentially useful resources.
Refine, review, and save any potentially useful results.
If you have found hardly any, don't just give up and change your topic...
Contact your liaison librarian, and if they are unavailable, then Ask a Librarian first!
Changing your topic to something that is "easier to research" may seem like an easy fix for now, but as you progress in your coursework, most likely you will be more restricted in the choices you can make.
