Mr. Lincoln's Virtual Library highlights two collections at the Library of Congress that illuminate the life of Abraham Lincoln (1809-1865), the sixteenth president of the United States. The Abraham Lincoln Papers housed in the Manuscript Division contain approximately 20,000 items including correspondence and papers accumulated primarily during Lincoln's presidency. Transcriptions and annotations for the Papers are available through a cooperative agreement with the Lincoln Studies Center, Knox College. The We'll Sing to Abe Our Song!" online collection, drawn from the Alfred Whital Stern Collection in the Rare Book and Special Collections Division, includes more than two hundred sheet-music compositions that represent Lincoln and the war as reflected in popular music. In addition to the sheet music, the Stern Collection contains books, pamphlets, broadsides, autograph letters, prints, cartoons, maps, drawings, and other memorabilia adding up to over 10,500 items that offer a unique view of Lincoln's life and times."
