The material on this Web site emanates from the personal collection of ephemera accumulated over a 35-year period by Dr. Richard J. Oestreicher, Associate Professor of History at the University of Pittsburgh. The collection emphasizes ephemeral items (i.e., made for one time or brief usage and then likely to be discarded) from the 1890s to the present and includes periodicals, photographs, letters, pamphlets, books, posters, flyers, labels, pins and other objects.
While the majority of these items were produced by the Socialist Party USA (SPUSA), Communist Party USA (CPUSA), Students for a Democratic Society (SDS), or organizations linked to them, the collection also includes material from a wide variety of other organizations and movements as well as from unaffiliated activists and radical intellectuals. The collection now resides at the University's Archives Service Center.
