This is from the authors note at the front of the new book.
“Shipwrecks of the Western Hemisphere was published in 1971 and later republished as Shipwrecks of the Americas and New World Shipwrecks. These books contain shipwreck data that I researched prior to 1968. Since then I have continued researching Western Hemisphere shipwrecks in primary sources, and this volume will include many shipwrecks not mentioned in my earlier books. I have never published any of my research on Old World ship losses, but have used it to locate wrecks, primarily in the Mediterranean, Atlantic Ocean, Indian Ocean, Far East, Australia, and the Philippines.
This book contains comprehensive information about the richest ships lost during the Age of Sail. The losses span the globe…”
The book also contains only vessels whose cargo is valued at a minimum of $10 million. (The $10 million is market value and includes astrolabes, cannon, ceramics, etc. not just silver and gold.)
102 pages of NEW WORLD shipwrecks and 276 pages of OLD WORLD shipwrecks
