You'll want to be sure to cite your sources using the proper format. Most English professors prefer the Modern Language Association (MLA) style. You may have your own MLA style guide from class but if not, here are a few resources to help you.
Pro Tip: Many databases, including OneSearch, offer a handy citation generator right there. Look for a "Cite This" sort of link (you may have to click the title), grab your MLA citation, and paste it into your Bibliograhy/Works Cited/References page. Be sure to check against one of the guides to ensure it's correct (capitalization, punctuation, did it include all required info?) and you are good to go.
