I have copied from the National Archives site the following about the Declaration of Independence. (For information about what happened to lead up to this, go below this blog post and read the one for June 1776.)
From the National Archives site:
Jefferson drafted the statement between June 11 and 28, submitted drafts to Adams and Franklin who made some changes, and then presented the draft to the Congress following the July 2nd adoption of the independence section of the Lee Resolution. The congressional revision process took all of July 3rd and most of July 4th. Finally, in the afternoon of July 4th, the Declaration was adopted.
Under the supervision of the Jefferson committee, the approved Declaration was printed on July 5th and a copy was attached to the "rough journal of the Continental Congress for July 4th." These printed copies, bearing only the names of John Hancock, President, and Charles Thomson, secretary, were distributed to state assemblies, conventions, committees of safety, and commanding officers of the Continental troops.
On July 19th, Congress ordered that the Declaration be engrossed on parchment with a new title, "the unanimous declaration of the thirteen united states of America," and "that the same, when engrossed, be signed by every member of Congress." Engrossing is the process of copying an official document in a large hand. The engrosser of the Declaration was probably Timothy Matlock, an assistant to Charles Thomson, secretary to the Congress.
But to me the most important part of this process was the July 19th NEW TITLE of UNANIMOUS DECLARATION of the thirteen UNITED states of America!
