In the mid nineteenth century, publishers printed the lyrics to popular songs, without their tunes, on small sheets called song sheets, handbills, or broadsides. These sheets were often illustrated with a woodcut scene or portrait and sold at gathering places where people sang together. Duke's collection of American song sheets includes 1,981 of these ephemeral productions, from "The Star Spangled Banner" to "Pop Goes the Weasel," forming a rich source for research on American society and culture. The American South and the Civil War era are especially well documented, including well over one hundred Confederate broadsides. The collection also includes carrier's addresses, non-musical poetry, and other ephemeral verse. Publishers represented in the collection include: J. Andrews, A. W. Auner, Bell and Company, James D. Gray, Johnson and Company, Charles Magnus, H. de Marsan, T. M. Scroggy, St. Clair Smith, H. J. Wehman, J. Wrigley, and others.
