By January 1942 the Book Production War Economy Agreement regulations came into force which determined rules on paper quality, type size and margins. Consequently Penguin eliminated dust jackets, trimmed margins and replaced sewn bindings with metal staples. Aside from the noticeable deterioration in the appearance of paperbacks it became a practical impossibility to publish books of more than 256 pages resulting in some titles falling out of print for want of material. In addition to their paper allocation Penguin secured a deal in late 1941, through Bill William's connections with ABCA and CEMA, with the War Office to supply the troops with books through what would be known as the Forces Book Club. Penguin would receive 60 tons a month from Paper Supply in return for 10 titles a month in runs of 75,000 at 5d.
