You should submit an annotated bibliography of at least four sources to be used in the refutation speech. The annotated bibliography should properly document your sources, summarize their main points, and explain how they will be useful in preparing your speech. At least two of the sources should be academic (e.g., books and academic journals), and all the sources should be credible (e.g., established media [i.e. not Buzzfeed], organizations, or think tanks).
