I have a 22nd edition, 1985, and it works fine for me. It covers the early NC machines, which were just becoming more popular in industry at that time. On a whim, I also bought a brand new reprint of the 1st edition (1914) for really cheap, under $20 as I remember. The first edition is a really interesting read, and goes more in to depth on things like heat treating, steel making, and other subjects. The most amazing thing about the first edition is how savvy machinists were in those days. We are not so "advanced" as we sometimes think.
