...there are many campaigns that are no longer active or have relevance. The learnings from that can be made public.

Sure, that could have value. It would require a long term pre-publication plan that says, "At some point, I'm going to trash this successful campaign so that I can write a book." I don't know that you do that though, do you? If you're making $10,000/yr with AdWords, would you really trash that so you could make $10,000/yr with a book that's going to be "stale" within a year or two?

FWIW Perry Marshall's basic guide to AdWords is a good start for most people.

With the recent switch over to enhanced campaigns this year I'm not even sure looking at a successful past campaign would be that great.
