The Duke University libraries have several digital collections available on their websites. One of these is the American Song Sheets collection, which contains around 1800 song sheets, all from the 19th century. It was customary during the 19th century for publishers to print just the lyrics of popular songs on a single sheet, usually illustrated with a drawing. These became known as song sheets, handbills, or broadsides. The illustrations and the lyrics to these songs provide an insight into popular themes of the time. The collection contains a lot of broadsides from the South and the Civil War era in particular, so it can be useful for understanding homefront morale during the war or for studying the larger context of the 19th century. There are two options for searching the collection: by keyword on the main page or by using the index that allows the user to search the text of the song lyrics. For those interested in the music to accompany the words, there is also a searchable database of sheet music.
