We would like to thank all those who helped to uncover the material produced in this book. Extensive research was carried out by Paolo Brini, Francesco Giliani, Alun Morgan, Rob Sewell and Harry Whittaker in different archives and universities. We would like to specially thank Carol McCullam and Philip Wallace from the Glasgow Caledonian Archive of the Trotskyist Tradition; the universities of Hull and Warwick where the archives of Jock Haston and Jimmy Deane are hosted; the Senate House archives of Al Richardson in London; the Trotsky archive in Harvard.

The bulk of the research was based on the archives of Sam Bornstein and Ted Grant which were reorganised and put into order by Francesco Merli. We also thank Alan Woods for providing us with WIL and RCP internal documents from his personal archives that would have otherwise been impossible to trace.

Many comrades have helped in transcribing and proofreading the material for this project. Special thanks to Miriam Díaz Crespo, Lynne Faulkes, Julianna Grant, Ana Muñoz, Harry Nielsen, Rob Sewell, Maarten Vanheuverswyn and Harry Whittaker. We would like to express our special gratitude to Francesco Merli for the systematic research and editing work and for taking up the task of coordinating the project. Thanks to Emil Vaughn for his proofreading and pioneering work on the Ted Grant archive website and to Maarten Vanheuverswyn, Niklas Albin Svensson and Manuel Reichetseder for guaranteeing its regular update. A special thanks to Fred Weston and Harry Nielsen for the final proofreading of all the texts published here, and to Steve Jones and Mick Brooks for the index.

For this second edition we would like to thank Victor Murray Vedsø for the new cover, Jesse Murray-Dean for laying out the contents, Manon Powrie for proofreading, and Solomon Dobbs for procuring new material from the Records of Jock Haston at Hull History Centre.
