American Time Capsule: Three Centuries of Broadsides and Other Printed Ephemera
"The Printed Ephemera collection at the Library of Congress is a rich repository of Americana. In total, the collection comprises 28,000 primary-source items dating from the seventeenth century to the present and encompasses key events and eras in American history. An American Time Capsule, the online presentation of the Printed Ephemera collection, comprises 17,000 of the 28,000 physical items. More are scheduled to be digitized in the future. While the broadside format represents the bulk of the collection, there are a significant number of leaflets and some pamphlets. Rich in variety, the collection includes proclamations, advertisements, blank forms, programs, election tickets, catalogs, clippings, timetables, and menus"
