There's no real distinction. If the name Hikaru had never appeared onscreen, it wouldn't matter how consistently it was used offscreen or in how many sources. Nor would it matter that nobody on the staff seemed interested in creating a canonical first name for Sulu. In the absence of the producers paying attention to such a tiny detail, I would say that whatever is used consistently offscreen should count the same. It would be no huge task for the producers to finally decide to use it, as happened in TUC.
Yes, but that's exactly the point. They're free to use it if they want. Non-canonical isn't forbidden, just optional.
If the policy is no longer enforced because Gene is no longer in charge, then why has there been no movement to include non-televised media and have it treated on the same level as episodes?
Because they're
not on the same level. Tie-ins are a supplement, a side branch. They're written by freelancers, outsiders hired to do a job, not by insiders. They're read by a tiny fraction of the audience, and contribute a tiny fraction of the franchise's profits. And making a TV show or a movie is a full-time job; TV producers simply do not have
time to keep abreast of tie-ins. Nor can tie-ins be produced fast enough for it to be practical. It is simply a logistical impossibility for a TV series to follow the lead of an ongoing book series, because the pace of the publishing business is glacial in comparison to that of the TV business. It
has to be the other way around.
Besides, why should the tail wag the dog? Why should the creators of the original work be obligated to conform to the ideas in supplemental literature rather than having the freedom to come up with their own ideas? Tie-ins are supposed to support the original creation, to supplement it, not to pre-empt it.
And you will find no franchise in all of fiction where tie-in material is treated on the same level as the core canon. Sure, Lucasfilm claims that all
Star Wars material is canonical, but Lucas doesn't hestitate to contradict it when he wants to do something else in a movie. Functionally, the relationship of canon to tie-ins is no different in
Star Wars than it is in
Star Trek; the only difference is in the relation of tie-ins to each other (SW tie-ins are required to remain consistent with each other, but for ST tie-ins that's optional).
Why have the majority of non-novel Trek books been simply rehashes of existing information, as has been pointed out?
I don't think that's true at all. You're falsely generalizing what someone said about one book, the
DS9 Tech Manual, as it relates to one other book, the
TNG Tech Manual. Looking over the "non-novel Trek books" on my shelf, I see an eclectic assortment of them, and those that fall into the "fictional nonfiction" category, such as the tech manuals,
Star Charts, and the like, are not mere rehashes of each other at all. Besides, most of those books that have been published in the past couple of decades have been by TV-Trek production staffers such as the Okudas and Geoff Mandel. So it wouldn't make sense to list them as outside ideas that the production staffers are ignoring.
It's fair to say that a majority of producers don't slavishly ignore anything non-televised because of Gene's policy, but they haven't made much effort to include it either.
They don't have to. It's their show; they have the right to take it in whatever direction they want. Sure, I'd like it if they acknowledged the stuff I wrote, but I'm fully aware that I'm just visiting in their backyard, borrowing the toys they own. I don't have the right or the inclination to ask them to follow my lead.
You have to do that if you expect the fans not to continue believing the policy is valid. Even if the memo can be considered a dead letter, that doesn't change the fact that Gene's name still carries a lot of weight in the fanbase. In the absence of a producer saying "we're no longer bound by Gene's old policy. We will be including (insert source here) as canon..." fans will default to what they know as the rule.
There's no such thing as "the fans." People are always expressing their own personal interpretation of things and asserting that "the fans" all feel the same way, but that's crap. There is no opinion that all Trek fans have in common. Sure, there's a faction that takes this whole "canon" nonsense ultra-seriously and doesn't understand how the business works, but that doesn't affect the actual production of the shows or the books. The producers' job is to produce the shows and movies, not to lecture on the definition of canon. Roddenberry felt the need to assert a definition of canon, but that was his particular hang-up.
I wholeheartedly agree. Wouldn't you agree, though, that the franchise would benefit from making this percentage larger? Shouldn't it make an effort to reach more fans in more ways than just what goes on the screen?
No, I don't agree. It would be nice if more people read the books, sure, but 1-2% of a decent-sized audience for a TV series is a very, very large audience for a novel series. Everything's relative.
And I reject the notion that there's any correlation between fans' attitudes toward canon and their interest in reading books. Sure, as KRAD mentions, there are a number of people out there who scoff at anything non-canonical as beneath their notice; but I believe that if they were genuinely interested in reading at all, they wouldn't let that attitude stop them. More likely, it's just symptomatic of a broader devaluation of reading as opposed to TV/movie viewing or playing video games. So some kind of official declaration of pseudo-canonical status for the books, even if such a thing could ever be practical or meaningful, wouldn't really have any effect on reading rates.
Cause that canon media isn't going to be produced on a regular basis forever. What will Paramount fall back on when it reaches a point where it chooses to no longer produce eps and movies?

Trek literature first came into its own in the 1970s, a time when Paramount had already chosen to no longer produce episodes and movies. That lack of new "canonical" material (although nobody would've used that term back then) enhanced the success of Trek literature, because it was the only game in town, the only way to feed the fans' desire for new Trek. So if you think Trek lit is dependent on onscreen Trek for its success, you need to study your history more.
What context are you using for "trust" here? I'm a little confused. If you're saying that fans should not be trusted to make reasonable judgments over what they like, or over what should be considered worthy of being official (note I didn't say canon), then I would disagree with that.
What? You were talking about fans' "trust" in the source material. That's what I was responding to, the bizarre notion that there was some kind of "truth" in a work of make-believe and that fans would feel their "trust" in it could be betrayed somehow.
As I said above, enforcement isn't necessary. All that's necessary is for those in charge to remain indifferent, at best, to the idea of including offscreen material. That in turn reinforces the idea to fans that such materials do no count.
Again, "fans" are not a monolith. The only fans who would react that way are those who are already predisposed to think that way. And if you've participated in any of the eighteen thousand previous TrekBBS debates on this topic, you should be very well aware that there are plenty of fans out there (at least on this forum) who scoff at the notion that definitions of "canon" should have any bearing on their acceptance of the literature.
Don't get me wrong, I hear what you mean Christopher. I agree the audience is certainly there. But this is another area where the PTB could be doing more. Saying "well, it's just imaginary." is no excuse to pretend one can't make a good Trek game.
I never claimed it was an excuse. I'm not making any claims about the viability of video games one way or the other. I just find it a complete non sequitur to talk about definitions of reality when speaking about a video game that depicts a different reality every time it's played.
