Jo (Charles Joseph Antoine) Labadie, 1850-1933, was a Detroit anarchist, labor activist, and printer, who donated his personal library to the University of Michigan in 1911. Since then, the collection has grown to include 40,000 books, 800 periodicals, 20,000 pamphlets, and close to 1,000 pictures. Much of this material has been digitized, and users can approach it in two ways -- by touring an online exhibition created by the Special Collections Library or by starting at the Labadie Collection Home Page. The online exhibit mimics the structure of a physical exhibition mounted in September 2000; visitors can read through sections such as Birth and Early Life, Marriage and Family, John Stuart Mill (1806-1873), Anarchism, and The Haymarket Affair. Visitors follow links to images, or select Browse All Images, to proceed though the fifteen wall and floor display cases of the original exhibition.
