'''Canon''' is the noun used by Lostpedia to describe information that is known to be ''officially'' part of the ''Lost'' universe. Only canonical storyline information may be stated as ''fact'' on Lostpedia. 

The primary purpose of this article is to note 
"canon" by Lostpedia 

It is important to note that when no conflict of storyline information exists, and when the source of such information is ''other than'' the episode, Lostpedia's judgement in this Canon policy is ultimately an ''arbitrary'' one that has no other use than self-consistency ''within this website only''.

In other words the ''purpose of this policy article is not to judge what information may be considered "real"'' in the fictional universe of the storyline of ''Lost''.  

Neither is the purpose of this article to exhaustively compare all potential and future sources of storyline information; as sources of information change and evolve, site policy may therefore also be subject to change. 

Broadly speaking, canonical information is always approved by the creative staff of ''Lost'' (the creators, directors, and writers) and released through various official outlets. Information from other people and/or other outlets is considered CategoryNon-Canon|"non-canon".

The primary official outlet is the television PortalEpisodes. Other official outlets include press releases, websites, podcasts, interviews, books, DVDs, and non-television episodes. If canonical information conflicts itself, information from the television episodes takes precedence. If two episodes contradict each other, the more recent broadcast takes precedence. If multiple contradict one other, the information in multiple episodes takes precedence (no matter the broadcast order). When citing canonical information on Lostpedia, always indicate the outlet it originated from (episode name, podcast number, etc.).

Other non-canonical or semi-canonical information can be included in Lostpedia when properly marked with sources cited.

Damon Lindelof and Carlton Cuse have stated on record that the following are canonical. The first four were cited in an interview with Entertainment Weekly http//www.ew.com/ew/article/0,,20179125_4,00.html, the fifth from a previous interview http//www.lostpedia.com/wiki/The_Lost_Experience, and the sixth from a producer commentary on the Lost The Complete Third Season (DVD)Access Granted and an interview with Gadi Pollack http//blogs.pcworld.com/gameon/archives/006458.html.

*''Lost'' episodes (noted by Lindelof as "the only ''true'' canon")
*''Lost Missing Pieces''
*''Lost Encyclopedia''
*Information released as part of DVD extras, such as the ''The New Man in Charge'' epilogue featured on the Season Six DVD. (this does not include DVD commentaries, bloopers and deleted scenes ''see below'')
*The Orchid Orientation film
*The ''Christiane I'''s search for the ''Black Rock'' from ''Find 815''
*Information about the Hanso Foundation and the Valenzetti Equation revealed in ''The Lost Experience''
*The Blast door map (Via Domus), the Incident Room, and the Locations (Via Domus)''Lost Via Domus''.

Carlton Cuse goes into greater detail about the issue of ''Lost'' canon in the Official_Lost_Podcast/March_10%2C_2008, 2008 Podcast. Ancillary materials such as deleted scenes, the majority of the storytelling in the ARGs, and other sources of information are considered apocryphal to varying degrees of semi-canon, and depend solely on how involved the executive staff are in the development of each.

The following contain varying degrees of canon, according to the writers. This list is considered comprehensive, but not final, and is subject to change.

*Official outlets for business or commentary. The creative staff of ''Lost'' also directly comments in the public media or retail media. This information is not part of the story of ''Lost'', but is still an official source of information.

*Official "story-telling" outlets other than ''Lost'' episodes. This information is considered part of the story of ''Lost'', even though it is revealed outside of the show itself. In these cases, canonical facts are revealed through a basis of non-canon storytelling; for example the information revealed in the Sri Lanka Video is canon, while Rachel Blake's ongoing story that revealed it is not.

Note Often, minor conflicts occur between canonical information revealed through official outlets other than ''Lost'' episodes. A summary or warning should be included on pages containing conflicting information. Unless consensus requires otherwise, Lostpedia policy is to include all official information as part of the canon. It is important for editors to cite sources in such cases, because it allows the reader to make their own judgement as to the canonic quality of the information, rather than relying on the ultimately arbitrary judgement of the fan community of Lostpedia.

There are many unofficial websites and media related to ''Lost''. Information from these outlets is not canonical. Information from these outlets must be clearly marked if included on Lostpedia, and should not be in the ''Facts'' section of any article.

The following outlets are examples of information Lostpedia considers to be unofficial, unreliable, or otherwise CategoryNon-Canon. This list is not comprehensive.

*Lost Wiki (website)The LOST Wikia
*Bloopers - Bloopers are minor production errors. Although they are visible on screen, they were not ''intended'' to be visible.
*Deleted scenes
*Information given on Enhanced episodes. These are provided by a third-party company, and not created or monitored by the production team.{{crossref/March 19, 2009}}
*Information on Wikipedia, IMDB.
*"Leaked" information or unofficial spoilers
*Private communications of ''Lost'' cast/crew
*Interviews by cast/crew that are not released on official channels (website, DVDs, etc) except those made by Damon Lindelof & Carlton Cuse.
*Unused materials made by cast/crew
**Unused parts of official screenplays
**Draft materials, storyboards, and items that were never intended to be final
**Episode promotional photos from ABC may contain inaccurate or deleted content
*Categorytheories or categoryparody articles on Lostpedia 
*False information, such as from CategoryHoax sources or unintentional errors by the media
*(categoryFanon) - information created by fans
*''Lost Via Domus'' - It has been confirmed by producers that the game's storyline is not "canon" to the show.  However, the Blast door map (Via Domus), the Incident Room, and the Locations (Via Domus)"canon" as per the producers commentary and what is seen on ''Lost''.  As such, while we will keep information on Via Domus on the site, interactions between the game and show characters should not be added to character articles, and information on the game will be kept in a seperate Via Domus area of the site. http//blogs.pcworld.com/gameon/archives/006458.html
* The Dharma booth video in the ''Dharma Initiative Recruiting Project''

Note Some believe that deleted scenes should be considered canonical, if no other information conflicts them.  Information on Lostpedia from deleted scenes must be clearly marked (sometimes called "apocrypha" or "deuterocanon").

==Mixed articles==
Where an article has content that is both part of canon and non-canon (or canon and semi-canon), then the canonical information should take precedent and be placed above any non-canonical (or semi-canonical) information on the page. The non-canon (or semi-canon) information should be placed under a separate heading, and clearly marked as such using {{Non-canon}} template. Which looks like this


In addition, whenever possible, the introductory paragraph for an article should ''only'' contain information ''shared'' between the canonical and the non-canonical (or semi-canonical) sources. Contradictory details should be limited to separate sections for the different media depictions, and explicitly pointed out as contradictions either as a footnote, or, if there are multiple contradictions, in a separate section.

An example for how this is supposed to look like when the subject of the article itself is presented differently in media of different levels of canonicity can be found on the page for the ''Christiane I''; an example for the subject of one or more sections of an article, but not the subject of the article as a whole, being portrayed differently in different media can be found in the "The search" and "Purported discovery of the wreckage" sections on the page for Oceanic Flight 815.

*''Bloopers'' These are not part of the canon.
**A trainer's hand on the horse in {{ep}}.
**Some local Hawaiian houses visible from the Pala Ferry port in ABC promotional media (although not in the episode per se) for {{ep}}.
*''Rebroadcasts of episodes'' When content in a rebroadcast conflicts with a prior airings, the recap information has canonical priority.
**The phrase heard by Boone on the Beechcraft's radio in {{ep}} "We're the survivors of Flight 815" was re-recorded for the recap show to make the phrase clearer.
*''Newer episodes'' The information in a newer episode has priority when conflicting with a previous episode. However, if multiple contradict one other, the information in multiple episodes takes priority (no matter the broadcast order).
**The change of Penny shown in Desmond's photograph in {{ep}} and {{ep}} in comparison to the other appearances of Penny.
