I just bought the Kindle edition of Norman Friedman's
Naval Weapons of World War One on Amazon for $9.99. Amazon wanted $55 for the physical edition, so I'm pretty pleased at the moment. Looks like Seaforth Publishing has been slowly making electronic editions of their books available this last year, and considering how much I spend on naval reference books, that can only be a good thing.
Still, you can't beat a big hardcover book when it comes to detailed diagrams and schematics...
