Wikipedia:POVFORK

A content fork is the creation of multiple separate articles (or passages within articles) all treating the same subject. Content forks that are created unintentionally result in redundant or conflicting articles and are to be avoided. On the other hand, as an article grows, editors often create summary-style spin-offs or new, linked articles for related material. This is acceptable, and often encouraged, as a way of making articles clearer and easier to manage. Examples of this might be the cuisine of a particular region forking from an article about the region in general, a filmography forking from an article about an actor or director or a sub-genere of an aspect of culture such as a musical style.

The most blatant POV forks are those which insert consensus-dodging content under a title that should clearly be made a redirect to an existing article; in some cases, editors have even converted existing redirects into content forks. However, a new article can be a POV fork even if its title is not a synonym of an existing article's title. If one has tried to include one's personal theory that heavier-than-air flight is impossible in an existing article about aviation, but the consensus of editors has rejected it as patent nonsense, that does not justify creating an article named "Unanswered questions about heavier-than-air flight" to expound the rejected personal theory.

The creator of the new article may be sincerely convinced that there is so much information about a certain aspect of a subject that it justifies a separate article. Any daughter article that deals with opinions about the subject of parent article must include suitably-weighted positive and negative opinions, and/or rebuttals, if available, and the original article should contain a neutral summary of the split article. There is currently no consensus whether a "Criticism of..." article is always a POV fork, but many criticism articles nevertheless suffer from POV problems. If possible, refrain from using "criticism" and instead use neutral terms such as "perception" or "reception"; if the word "criticism" must be used, make sure that such criticism considers both the merits and faults, and is not entirely negative (consider what would happen if a "Praise of..." article was created instead).

There are things that occur from time to time that may be mistaken for content forking.

Note that meeting one of the descriptions listed here does not preclude something from also being a content fork.
