Here again is one of Ken Cope's major reference works on the history of technological innovation. Anyone interested in wagons and carriages, particularly in wheelwrighting, and in the history of technology will enjoy and benefit from this book. Mr. Cope continues his series with an alphabetic listing of the inventors and builders of American carriage and wagon makers’ machinery and tools and, as before, accompanies his descriptions with many illustrations from old catalogs and trade journals. There is, as well, a comprehensive Glossary of terms. Anyone interested in wagons and carriages, particularly in wheelwrighting, and in the history of technology will enjoy and benefit from this book.
