`The IWW: Its First 100 Years’ is a comprehensive history of the union of the United States based anarchosyndicalist labour union IWW.

But it is the only general history to give substantive attention to the IWW’s successful organizing of African-American and immigrant dock workers on the Philadelphia waterfront, the international union of seamen the IWW built from 1913 through the 1930s, smaller job actions through which the IWW, Wobbly successes organizing in manufacturing in the 1930s and 1940s, and the union’s recent resurgence.
