Yes, which is why both of the countries I actually mentioned -- the United States and Russia -- contain territory that goes beyond a single continent. The whole point of my analogy is to say exactly what you just said: that a personal continuity can include -- or exclude -- both canonical and extracanonical material. But personally counting a tie-in novel doesn't make it part of your "personal canon" any more than Hawaii is part of the USA's "national continent." Each fan has one's own personal continuity, while the studio has its canon. That's the distinction.
Yeah, rereading that now I see that, serves me right for getting in a thread about canon.
I'm going back to my personal country now, hold my calls everone...
