In general,
Star Trek novels are not considered part of the canon. There are also conflicting messages concerning "non-fiction" reference books such as
The Star Trek Encyclopedia,
Star Trek Chronology,
Star Trek: The Next Generation Technical Manual, and
Star Trek: Deep Space Nine Technical Manual. Unlike the novels and novelizations, these reference manuals have never been explicitly named as non-canonical, and the fact that they were officially sanctioned by Paramount and given to episode writers as guides serves to give them an aura of credibility. Roddenberry himself considered it part of the "background" of
Star Trek. Similarly,
Michael Okuda and
Rick Sternbach, artists and technical consultants since
Star Trek: The Next Generation and the authors of several of these reference books, considered their work "pretty official". However, they stop short of naming the books canonical, leaving the debate open.
Star Trek writer and co-producer
Ronald D. Moore dismissed such material, saying that, although the writing staff would often consult reference materials, they did not consider them canonical, reserving that title for the episodes and films. However, in a series of posts to the official
Star Trek website's forums, Viacom Senior Director Harry Lang established his opinion that the reference books are canonical, saying "Only the reference books (tech manual, encyclopedia, etc ...) and two books by Jeri Taylor are considered canon outside the tv show and movies." The
novelizations of episodes and movies are not considered canonical. This is a tradition that also goes back to Roddenberry himself. His novelization of
Star Trek: The Motion Picture includes many tangents and new information. It reveals, for instance, that the woman who dies in the transporter accident was Kirk's former spouse. While this novel filled in many gaps left in the movie, it has been said that Roddenberry himself thought it should not be considered canonical:
Star Trek comic books and magazines are generally not considered part of the canon. Nothing that takes place in
Star Trek games, the
Star Trek: The Experience attraction, or any other licensed material is considered canonical, nor are any unlicensed works such as
Star Trek fan productions. ==See also==
