I first read this in The IWW: Its First Fifty Years edition, probably in the middle of high school before reading the Rebel Voices anthology, then reread it in its updated edition. There is now a further update subtitled "Its First One-hundred Years". I must have loaned out the previous two editions as neither appear on the bookshelves here. If those anarchist thieves read this, return would be appreciated (or, better, pass 'em on...).
