The information recorded in these daybooks is then transferred to the general ledgers. Smaller multihulls may be collapsible and trailerable, and thus suitable for daybooks and racers. In early 1915 Weston began keeping detailed journals he later came to call his "Daybooks". In his "Daybooks" he provided an unusually detailed record of his evolution as an artist. These daybooks are not part of the double-entry bookkeeping system. Edward Weston - Daybooks - May 24, 1930.
