is inside jokes inserted by the production staff. Other kinds of information, such as the biographical information seen on a computer display in the Enterprise episode "In a Mirror, Darkly", has been stated to not be "hard canon". Films All official Star Trek feature films are also considered canonical. While not explicitly stated, the most complete released version of the films, including scenes missing from the theatrical version of a film but included in home releases or director's cuts, appear to be canonical. One scene, deleted from Star Trek II: The Wrath of Khan, revealed Peter Preston as the nephew of Scotty. Peter Preston is included in the canon database at StarTrek.com. Adding confusion to the issue is the fact that Roddenberry is quoted as saying that he disliked the films, and "didn't much consider them canon". There exists no definitive list of which films in particular Roddenberry disliked, or what elements in them he did not consider canonical. For example, the reference book Star Trek Chronology states that Roddenberry considered elements of Star Trek V and Star Trek VI to be apocryphal, but it does not specify which particular elements in the films Roddenberry objected to. The canonicity of extra features found on home DVD releases, such as deleted scenes, has never been explicitly addressed. "Reboot" films (Kelvin Timeline) Star Trek (the 2009 film), Into Darkness and Beyond occur in a separate timeline from the rest of the series. In June 2016, for the computer game Star Trek Online, CBS named this the Kelvin Timeline, after the USS Kelvin, which was attacked and destroyed in the opening scene of Star Trek. Former names for this universe have included the alternate timeline and the reboot series. Events depicted in the Kelvin Timeline films that occur prior to the temporal incursion that creates the new time line, such as the destruction of the planet Romulus, have been referenced in later "prime timeline" works such as Star Trek: Picard and Star Trek: Discovery. Publications Original tie-in novels Many of the original novels published by Pocket Books are not considered part of the canon. This was a guideline set early on by Gene Roddenberry, and repeated many times by people who worked with him. And as long as Gene Roddenberry is involved in it, he is the final word on what is Star Trek. So, for us here – Ron Moore, Jeri Taylor,
