The Joseph A. Labadie Collection is the oldest research collection of radical history in the United States, documenting a wide variety of international social protest movements of the nineteenth and twentieth centuries. It is named for anarchist and labor organizer Joseph Antoine Labadie (1850-1933).

Use of the Labadie Collection is open to all researchers, although special conditions govern the use of manuscript materials and researchers are urged to write or call ahead. Cataloged books, serials, pamphlets, and archival collections may be found in the University Library's on-line catalog, Mirlyn. A listing of some other materials can be found on the menu to the left. Duplication services are available, subject to the condition of the material and copyright or donor restrictions.
