The club supplied a book chosen every month by Gollancz and his panel (Harold Laski and John Strachey) to its members, many of whom took part in one of the 1,500 Left Discussion Groups scattered around the country. The books and pamphlets with their distinctive covers—orange for paperback (1936–1938) and red for hardback (1938–1948) editions—bore the legend "NOT FOR SALE TO THE PUBLIC" and sold for 2s 6d to members. Many titles were available for sale only in the LBC edition, with monthly 'choices' received by all members; there were also reprints of current socialist and 'progressive' classics for members to buy. The volumes covered history, science, reporting and fiction and a range of other subjects, but always from a left-leaning perspective.
