Despite its large membership and popular success the Book Club was always a huge financial drain on the publisher, and the advent of paper rationing at the onset of the war meant that the club was restricted to just one monthly title. To replace the book club's additional choices and augment the LBC selections, Gollancz launched the "Victory Books" series, a series of shorter monographs available to the general public. These included two of the biggest selling publications of the entire War period: "Guilty Men" (July 1940) by "Cato" (Michael Foot, Frank Owen and Peter Howard) and "Your M.P." (1944) by "Gracchus" (Tom Wintringham).
