Google Books lists several, including: Vincent St. John, "The IWW: Its History, Structure, and Methods" (1912) Paul Brissenden, "The IWW: A Study of American Syndicalism" (1919), Lenny Flank, "IWW: A Documentary History" (2007) (To the question of well-researched, that I cannot answer.) As far as I can see, only Brissenden is available online. Charles McCann
