Ah, remember when in middle school you could use Wikipedia as a source for presentations and not have to delve deep into scientific articles and books? *cries in college student*
Bruh, just use Wikipedia, but then quote the sources quoted on Wikipedia, lol.
Disclaimer: Don't actually do this for a class in your major, though. However, Wikipedia can still be an excellent place to start finding some useful resources and articles.
I agree, Wikipedia can be a great starting point. A lot of articles about certain topics go into great detail but don't go over the situation as a whole, so if you only read them you might end up missing the forest for the trees.
