The one and only, covers everything you can do on a Myford, and therefore on a larger lathe. Tools, tapers, modifications, lathe built tooling etc etc.
As mentioned by CRB, the Sparey book, which is practically a necessity to start with. You'll find various older workshop series volumes which cover lathe work in quite some depth. There was a three volume set by Caxton, I believe, and an eight volume set of which the publishers name eludes me at the moment. They're useful in that they cover far more than merely lathe work.
Another vote for the sparey book. And a more general workshop based book I have is "Metalworking Sink or Swim: Tips and Tricks for Machinists, Welders and Fabricators" and when you start getting more into it, machineshop trade secrets by James harvey is chock full of useful ideas and tricks.
And if you want the most informative specs and specific details on anything to do with machinery, but it has to be said in a indepth not beginner friendly format, there is the machinists bible, aka Machinery Handbook. Since your not using space age materials on a cnc, you can buy one years old off ebay and it'll still be useful.
