If I recall my MLA guide correctly from years ago, you don’t need to cite anything for common knowledge, “John Adams was the second president of the United States” being an example of common knowledge. If you needed to cite, you should cite primary sources like newspapers, journal articles, or biographies; not secondary sources like textbooks or encyclopedias.
