Should titles of constitutions be italicized?
Titles of constitutions, like titles of other laws and acts, are not italicized or enclosed in quotation marks. However, titles of individual published editions of constitutions are italicized and treated like titles of any other published work. Below, the title of the United States Constitution is not italicized or enclosed in quotation marks when the document is referred to in the running text, but it is italicized in the works-cited-list entry, where it refers to a specific published work.
The United States Constitution grants all American citizens a wide range of rights, including the right to free speech.
