The IIlustrated Encylopedia of Ships, Boats, Vessels an other Water-Borne Craft
The content of book involved types of craft, reader's actions, glossary and bibliography.
Ultimate authority hardly needs to be pointed out that a separate volume might will be written about almost every single entry contained in this book, so it should be understood that each entry is basically an identification only, although often with some historical background, and where necessary a more detailed examination of important sub-types.
