I see several old copies available on eBay.

Is there a particular edition/year that is considered "best" in some
way?

(Such as: Better illustrations? Easier-to-understand writing style?
More applicable to current machine designs? Layout or presentation of
information? Other considerations?)

I am a lurker w/o a lathe - who will someday get one; in the meantime
would like to bone up on the basic principles.
