It's far more complicated then that as shown by the Crisis on Infinite Earths: The Compendium. Thanks to a goof we don't know if Earth-Forty-Six ("Earth 2B") was "Alternate Earth-Two", "Earth-E", or some other Earth.

The Compendium does show that there were a host of parallel Earths some of which involved alternative versions of nearly all the Justice League as well as Superboy so the claim "any story involving Superboy must be on E-1" is deader then the proverbial dodo.

More over, like it or not in the form of Earth-Twelve and Earth-Thirty-Two Earth-B is a "thing" and even if you keep things to Earth-Thirty-Two there is still an ridiculous amount of stories and comics that got put there officially.

Finally, we must be careful of using anything that was fan created before the Compendium came out or creates fan things like Earth-Hostess and Earth-1278.
