    • Look at the information itself. Does it tell you how to cite it?
    • Use Noodletools NoodleBib Express in MLA format.
      • Keep your information window open while you work in Noodletools.
      • You may be looking at a general website, or a print source available on the web. It will ask you whether it was from a online database, and the name of the database. Fill in all information and let Noodletools generate the citation.
