19th century Register Books

In the 19th century, a fierce rivalry between shipowners and underwriters shaped the history of maritime registration, ultimately leading to the formation of Lloyd's Register of British & Foreign Shipping in 1834. This era saw revolutionary changes in shipping, from sail to steam and timber to steel.

Early 20th century Register Books

By the early 20th century, Lloyd's Register had grown into a truly global institution. Rapid advances in shipbuilding, propulsion, and refrigeration technology transformed maritime trade, reshaping the Register Books. Through two world wars, these records became so vital they were classified as secret.

Mid-20th century Register Books

The mid-20th century marked a transformative period for Lloyd's Register, as global shipping expanded while British dominance declined. With growing interest in East Asia and the 1949 amalgamation of rival society The British Corporation, this era left a distinct mark on the Register Books of the time.
