You're right. This is a good approach.
I am generally really not into compilations. I want an LP, as a statement, which existed at the time. It is not a philosophical thing: just my listening habits. My worst is a gigantic undifferentiated box set.
Something like the three Herds compilations are quite historical though, so that does sound like a sensible way in, as well as the 1970s recommendations that people have kindly made.
