Thomas Jefferson's draft of the Declaration of Independence went to the second Continental Congress, where representatives made many changes and additions. The revised document, which included some notations by Jefferson indicating appropriate places for pauses and points to be stressed when the words were read aloud, then went to a local Philadelphia printer named John Dunlap. The draft was set in type and a proof copy run. Unexplained quotation marks around phrases were discovered on one surviving proof copy of the first printing of the Declaration. Scholars have suggested that these printed marks may have been an effort to reproduce reading or emphasis marks on the now missing manuscript copy of the Declaration. As the document was put in its final printed form, these markings were eventually removed, although wide spaces between phrases provide evidence of their existence. With the marks deleted a few hundred final copies were printed for distribution. After those couriers carried these broadsides to many places in the colonies, where they could be read to crowds or printed in newspapers for the people to know why Congress had decided to break with the king. In fact as a small boy a future president of the United States, Andrew Jackson, learned of the Declaration in a local paper and after being inspired by what he read would join the Continental Army when he was barely a teenager! More than two centuries later only twenty-five of the broadsides printed by Dunlap are known to have survived.
