Sources about Macbeth

[dargok]

Hi. I am doing a highschool research project about Macbeth, and I'm lacking bibliography. Where can I find articles or sources that I can use?
My project is about whether Macbeth could have resisted the witches' influence. I have a lot to write about it, but I can't find sources to base it on.

I would start by asking for some help from your local librarian. He or she would know if your library had some supplemental texts to help you with your research. You could also give Google Scholar (http://scholar.google.com/) a try, but it often provides only partial sources.
