According to the Georgetown University Library, it is not necessary to cite the Declaration of Independence of the Constitution in your Works Cited/Annotated Bibliography because they are such well known works. However, you must cite them in your text.
Here's how the Georgetown University Library recommends citing these documents in-text:
Declaration of Independence
The first time you mention the Declaration of Independence in your text, add the institution author (U.S.) and date (1776) in parentheses.
Example: The Declaration of Independence states that the government's "just power" is derived "from the consent of the governed." (U.S. 1776)
After you have done that once in your text, you don't need to include (U.S. 1776) again.
When you are citing the U.S. Constitution, if you are referring to a particular section of the document you should mention the specific article, section, and clause in your text. Georgetown University Library recommends choosing one of two ways to do this.
Example 1: The Constitution of the United States, Article 1 (sec. 7, cl. 1) dictates that all revenue bills must originate in the House of Representatives.
Example 2: The U.S. Constitution (art. 1, sec. 7, cl. 1) dictates that all revenue bills must originate in the House of Representatives.
