If you can only have three web pages, you might want to do those first to get them out of the way. You can search for books that are related to your topic and use them in your bibliography. Google Books and Amazon are good places to search. Also try Google scholar (scholar.google.com), where you can search for journal articles to use. Another way to find research articles and books is to find the Wikipedia entry on your subject, and scroll to the bottom. See what sources are used there, and see if you can find those sources online or in your local library. Many journal articles and books (or at least abstracts and information about them) can be found online and used to create an annotated bibliography.
