Maybe, but for every person who only accepts Trek TOS or old/new BSG or Who there's someone whose personal <insert your favorite word here> includes the official canon material PLUS fan fiction, side stories, audio adventures, etc. etc. In fact, I'd wager there's more who add than subtract.
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. I've been adding tie-ins to my personal Star Trek continuity for decades, and yes, there are canonical episodes I exclude from it. I play that game just like anyone else does. I mean, my gods, I've written nearly 20 works of tie-in Trek fiction, all of which I count as part of my personal continuity, along with dozens of other novels and storie that my novels and stories interconnect with. So of course I'm aware that personal continuity is mostly about addition rather than subtraction.
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...
Indeed, even to return to one of the examples I used, the four Gospels of the New Testament are 'Canon' but contain different tellings of the life of Christ, each varying somewhat from the others. (I'm probably coming across as really religious here but I'm actually at best an Agnostic!)
Rather than us bickering over (under, beside, behind, etc.) canon (contenuity, whatever), let's just kick back and present examples of crossover craziness, be it illustration, Photoshopping, music videos or some other creative endeavor. Sincerely, Bill
And just like in Trek Fandom, there are many Christian theologians who will go through great pains to show how don't really contradict each other, tell the same story and fit together perfectly. The same is true of other religious canons, such as the canon of the Hebrew Bible/Tanakh, which--to cite one example--contains two differeing accounts of the creation of mankind.
Fifith Jesus is still my favourite. I still can't believe the robes they gave the sixth Jesus to wear...
In terms of trek/Dr. Who cross-overs, for the artists out there: TOS meets fourth Doctor Tennant should have been on Enterprise-D (more work with Pat) Matt Smith with JJ and Pine. It gets a bit harder after that. Hartnell on the Orbit Jet. Second Doctor on Lost in space or the Time Tunnel Third Doctor On Voyage to the Bottom of the Sea...or UFO Fifth Doctor in Buck Rogers with Erin Grey Sixth Doctor on Red Dwarf of course. Seventh Doctor...hmm NuBSG--Stargate--or, of all things Game of Thrones. Eighth on Space Above and beyond Ninth in Alien
