I ordered this book sight unseen and paid the price. I was disappointed because the book offers very little in the way of new information other than repackaging: you can view all WW1 battleships in one place, then move to WW2 section and find all the ships that fought in that conflict; thus ship classes will appear in more than one place. But the line drawings were very disappointing and shaded in to boot. I could not recommend this book unless you are a relative newcomer to the field. All the World's Battleships Ed. by Ian Sturton of Conway Classics is much better value for the money.
