The source base behind the Liberty ship argument

The opening identifies the books behind the account and states a source limitation. A. R. Monroe Smith's Merchant Ship Types provides comparisons with other wartime merchant vessels, L. A. Sawyer and W. H. Mitchell's The Liberty Ships emphasizes the design's British ancestry, and Peter J. Marsh's Liberty Factory informs the Kaiser shipyard history. Frederick C. Lane's comprehensive Ships for Victory had not yet arrived as a physical copy, so a fuller treatment of the Maritime Commission was deferred. The limitation confines this account to its developed industrial and leadership argument while leaving detailed commission history for further research. The opening also establishes the central tension: the commission's ambition for an advanced merchant ship had to give way to a pragmatic design that reduced labor and construction complexity.
