This book provides a unique opportunity for the study of world history with focus on global shipping and maritime transit from earliest times to present. Gordon uses details of shipwreck recoveries and their salvaged cargoes as the basis for his concise discussions of wider period issues, such as technology, environment, and societal change, as his tracks from shipwreck sources offer opportunity for follow up discussion and pair well with world history texts. The book as a whole is an engaging series of single chapter reads, as each chapter differs in its documentation, discussion, and varying approach to global history.
