For the definitive history of every Trotskyist group and paper find, "International Trotskyism," by Robert J. Alexander, published by Duke University Press, a few years back. (Bolerium Books in San Francisco has a couple of copies for $85 in their latest catalogue at http://www.bolerium.com/ . American Labor & Radical History )It is over 1000 pages +, and is one of those books, like Wallerstein's histories of the transition from feudalism to capitalism, where the abundent footnotes are just as meaty as the text. Alexander also has a Greenwood Press book on the Lovestoneites, which while it doesn't have the verve of the new biography of Jay Lovestone by Morgan, has the virtue of having a better feel for the history of the left and labor.
For "Revolution and Truth" here is a URL. I found it a while back when on the alt.politics.socialism.trotsky newsgroup the R &T leader, Ian, was accused of assaulting a member of another group at a march in London. Back during the anti-apartheid/divestment struggles at Cal. Berkeley, the local Sparts were accused of same on members of the Black Student Union.
