No, I mean is this particular paragraph FROM the writer's bible or some version of it? Because I can't find that passage anywhere in the paper version I have that gives its date as 1967 or the downloadable one with the same date. That passage seems to be from the author of TMoST in which case it is retrospective, not necessarily original intent.

Here's a page from the 1967 version. "It is the largest and most modern type vessel in the Starfleet service."
