In the 1960s and 1970s, many of the traditional shipping companies trading or based in Liverpool slowly vanished because of containerization or competition from the passenger aircraft. Many of these shipping lines had been in operation since the early years of the 19th century and had provided links with the outposts of the Empire and the developing independent countries of the Commonwealth. They had been established in the days of sailing ships and had survived the transition from sail to steam and had provided a lifeline to the country in the difficult days of both world wars and the great depression of the 1930s. With a fascinating collection of newly unearthed photographs, shipping historian Ian Collard documents this important period of transition in the history of one of the world's most famous ports.
