From Bulbapedia, the community-driven Pokémon encyclopedia.
|| This article is a proposed policy for Bulbapedia.
Please discuss the proposed policy and suggest possible changes on the article's talk page.
This is a policy outlining what is and what isn't a valid source, and why it has become mandatory to source your additions.
Importance of sourcing
In the past, many users have left their edits unsourced, leading to confusion as to whether their addition is legitimate. As such, the staff has decided to make sourcing mandatory to make sure users cite their sources in the edit summary and aren't adding false information. If you leave an edit unsourced, your edit may be reverted.
Where the source comes from is also important. As usual, fansites are not valid sources. If a fansite has something that we don't, do not cite them as a source; instead, find where that fansite got their source and cite that instead.
New game information usually comes from a Nintendo Direct, an official site (in any language), or CoroCoro. Any information found elsewhere, such as a fansite or a forum will be rejected. News sites are credible, if they have cited their sources.
English dub voice actors must be sourced by asking the voice actors directly on any social media platform or by email. Playing by ear and/or going by the credits are not valid sources, even if the credits only lists those who appear in the episode, going by process of elimination is still playing by ear. To source, you must provide a link to the social media post or an image of the email you have sent and received.
Japanese voice actors are generally credited with a role in the Japanese version of the anime, so going by credits to verify a Japanese voice actor is acceptable.
New episodes or airdates
Generally, TV schedules will list new Japanese episodes and new airdates; you must link to either on image of the TV schedule or a direct link to the TV schedule. The same goes for dub episodes, link to the schedule where you found the airdate. Do not assume that the episodes are going to air weekly, as an episode may get delayed or skipped under specific circumstances.
New releases/release dates
Generally, release dates and ISBN numbers for new (and existing) manga volumes can be found on reputable booksellers' websites — predominantly Amazon (for Japanese, English, and international releases) as well as Barnes & Noble, Indigo, etc. for North American releases. Kinokuniya is also a good source for Japanese releases; likewise, Kinokuniya Singapore is a good source for English releases by Chuang Yi or Shogakukan Asia. Only the official listings and not user-generated listings should be used. Release information can also be sourced from the publishers' official web pages and from Diamond Previews.
Obviously, anything published in the manga volumes themselves is sourcable, including advertisements (for future/cancelled volumes) and "about the author" blurbs.
Any information provided publicly by a manga publisher (Shogakukan, VIZ Media, Chuang Yi (in the past), Shogakukan Asia, or an international publisher) via social media or their website is a credible source for use in Bulbapedia articles. Similarly, any information or statements from a manga creator, either via their personal web site, social media account, interview, etc, is credible for use in Bulbapedia articles.
As with other Pokémon media, fansites and forums should not be used as sources, especially if they themselves have no other source for their information. Reputable news sites may be used provided they have cited their sources (a press release, etc.)
The only sources acceptable to definitively confirm a Pokémon's origin are interviews with an official member of Game Freak or any notes/statements on promotional material or concept art. Social media posts from an official Game Freak staff outlining an origin of a Pokémon is also acceptable. This official staff member should generally be the one that designed the Pokémon. Statements from affiliates of Game Freak (e.g. The Pokémon International) are not valid sources unless they verify that their claim came from the designer themselves.
The above also applies for name origins as well, with interviews or statements from an official member of Game Freak (for Japanese name origins) or The Pokémon Company (for international name origins) staff.
