Well, I have no idea what you mean specifically by a scholarly website. You should clarify that. I mean, university websites could be considered "scholarly". That would mean Avenue falls under that category
But try starting on the library website and there's an entire research section. And subject and course guides are sometimes helpful.
Or if you just mean "real" websites when you say "scholarly", then just make sure the sources are legitimate (ie. government websites)
Hope this helps.
If all else fails, go the library and ask a librarian for help.
