The impact of IWW ('Industrial Workers of the World', otherwise known as 'Wobblies') has reverberated far beyond the ranks of organised labour. Originally published in 1964 and long out of print, Rebel Voices remains by far the biggest and best source for IWW history, fiction, songs, art and lore. This new edition includes 40 pages of additional material by Fred Thompson and Franklin Rosemont and a new preface by Wobbly organiser Daniel Gross.
