On Lostpedia, information is defined as writ if it known to be officially part of the LOST universe. In literature or religion, information with this authority is often refered to as canon (meaning rule). Because the story of LOST is revealed through different forms of media, multiple canons -- connected, but distinct -- compose the collective story.

The following policy defines what information is considered writ. Only writ information can be stated as fact in Lostpedia articles. For information regarding Lostpedia policy on theories and interpetation, see Theory Policy.

LOST's Creative Authorities

LOST is a collaboration of hundreds of artists, technicans, writers and businesspeople. Their collective contributions are guided and integrated into single artform by the directorial staff of the program: the directors, the head screenwriters, and the show's creators. These figures - hereafter "LOST's creative authorities" - have the authority to decide what becomes a part of the LOST universe (writ). On this page, information that Lostpedia considers to be approved by LOST's creative authorities as writ is refered to as sanctioned.

Additionally, information about LOST is now revealed through other forms of media, beyond the show itself. The Lost Experience, tie-in novels, and the like, as discussed in following sections of this article, are also defined by Lostpedia as legitimate sources of writ information. This is because these activities are also overseen and approved by LOST's creative authorities, and thusly have the same legitimacy as the show.


Canon is defined as information revealed through LOST itself. The canon is writ and takes precedence when contridicted by other writ information.


  • Televised broadcasts (currently, this is the primary medium)
  • Episodes on ABC.com and iTunes
  • Sanctioned releases on DVD.


  • Bloopers are not canon, as they are the result of minor production errors. In other words, even though they're visible, they were not intended to be visible. For example:
  • Contradictory information from later episodes or subsequent rebroadcasts supercede information from previous episodes if continuity is violated. These changes are usually negligible in impact to the storyline. For example:


Deuterocanon is defined as information revealed by sanctioned activites other than the show itself. The deuterocanon is writ.



  • Fan-made, scam, or hoax websites.

Ex cathēdrā

Ex cathēdrā information is defined as comments, made in the public media, by LOST's creative authorities. Information revealed ex cathēdrā is writ, but is not part of a canon. It should also be noted that ex cathēdrā comments are sometimes intentionally deceptive or misleading.



  • Information on IMDB or other unsanctioned websites
  • "Leaked" information and unoffical spoilers
  • Private communications of LOST cast/crew/staff
    • These were not intentionally revealed by LOST's creative authorities.


The apocrypha is defined as sanctioned materials that were offically excluded from the canons. This information is not writ, because the deliberate omission of these materials is for both technical and artistic reasons. Informally, it can be considered "offical background" to what is writ. The apocrypha is literally "hidden."



  • Draft materials, storyboards, and items that were never intended to be final.

Information that is not writ

There are a huge number of unsanctioned LOST-related websites and media, due to the popularity of the show. These are not considered writ by Lostpedia. This information is known as fanon. It can be difficult to discern fanon from canon; TCP/IP tools such as WHOIS can be useful in determining the legitimacy of a site. Some fanonic sources intentionally pose as canonic sources, and can be considered to be scams.

Theories are also not writ. See Theory Policy.

Marking writ information on Lostpedia

Information presented in articles as fact should always be writ. Differenciating between canon and deuterocanon are unnessasary, except when contridictions arise. However, common practice is to indicate the source of any writ information (episode name, TLE site, etc).

  • Ex cathēdrā information must be marked, including a reference to the source of the material (interview date, podcast number, etc).
  • Apocryphal materials must be marked with [[Template:Apocrypha]].
  • Articles with an unconfirmed status as writ or otherwise should be marked with [[Template:CanonWarning]] until a proper classification can be determined.
