Created and maintained by the Schoenberg Center for Electronic Text and Image at the University of Pennsylvania Library, this online document archive contains material related to "the causes, conduct, and consequences of the US Civil War." The collection is largely comprised of books, broadsides, cartoons, pamphlets, and other printed ephemera from 1830 to 1880. Drawing heavily on materials held by the Library Company of Philadelphia, the documents include speeches by Charles Sumner, cartoons by Thomas Nast, and promotional material from the Know-Nothing Party. The entire archive can be browsed by author, date of publication, title, or subject. Using a built-in viewer, each document can also be viewed in its original format, and visitors can zoom in or out on discrete areas. Finally, visitors can also search the entire archive by keywords, subjects, graphic elements, or date.
