Finding naval books beyond online searches

Naval research sometimes requires books that Google or Amazon cannot locate. Specialist booksellers supply another route: a Tokyo contact finds Japanese naval works, a Glasgow shop covers British shipyards, ship design, and railways, and a Dallas shop tracks down American publications. Personal contacts can help recover material that ordinary online searches miss. Translation creates a further obstacle after the book has been found. One reciprocal arrangement exchanges Japanese-to-English translation for explanations of engineering passages encountered in the translator's own research.
