In the book, ¹ appears on page 96 and ² appears on page 97, but both footnotes must be placed on page 97 due to the way that we transcribe the book. We changed the latter footnote on page 97 to ² to reduce confusion. The paper book abbreviates the Wobblies as I. W. W., which could cause the text formatter to break up the letters over two lines. One solution to overcome the text formatter is to write "I.W.W.", but the cramped phrase reads awkwardly. Modern history books use "IWW". I used the convention adopted by the paper book and hope that the reader is not too inconvenienced by the possible break of I. W. W. across two lines. Page 231: Changed "cooperation" to "coöperation" because every other spelling of that word and derivations had an oomlat. There were thirty-three occurrences of cöperation or coöperate or coöperate and even coördinate. The six occurrences of "coop" were either the name Cooper or the profession. My guess is that the publisher left out the oomlat here by mistake when hyphenating the word into two lines for spacing. Page 262: Every other item in the Bibliography has the date of the book in parenthesis with a period after the right parenthesis when the period is used. I have changed (1889.) after Terence Powderly's book to (1889). Page 270: Insert a comma in the index after "Industrial Workers of the World" and before "American Alliance . . .".
