Watson-Jones's textbook became known as "the bible."  It was reprinted 15 times during the author's lifetime and translated into  Spanish, French, German, Portuguese and Polish. "Throughout its publication, Watson-Jones found unique ways to demonstrate his theories and techniques, including acetate and radiographic overlays, question-and-answer formats, and a writing style that was not only instructive but interesting."
