The second draft, of the Gettysburg Address, probably made by Lincoln shortly after his return to Washington from Gettysburg, was given to his secretary John Hay, whose descendants donated both it and the Nicolay copy to the Library of Congress in 1916. There are numerous variations in words and punctuation between these two drafts. Because these variations provide clues to Lincoln's thinking and because these two drafts are the most closely tied to November 19, they continue to be consulted by scholars of the period.
