This page in a nutshell: This is a history of changes to content policy pages. Deletion and enforcement policy pages were also covered before 2012, and volunteers to continue that work would be appreciated. Please edit any of these pages as needed, or discuss on the talk page.
In WP:TITLE#National varieties of English, changed: "However, sometimes" to: "Very rarely," [a form that represents only minority local usage is chosen because of its greater intelligibility to English-speaking readers worldwide (e.g. Ganges rather than "Ganga").]
In WP:TITLE#Considering title changes, added: [Changing one controversial title to another,] "without consensus after discussion," [is strongly discouraged.] Added: [do not invent names] "or use extremely uncommon names" [as a means of compromising between opposing points of view.]
In WP:NPOV#Due and undue weight, added: [Giving due weight and avoiding giving undue weight means that articles should not give minority views] "or aspects" [as much of, or as detailed, a description as more widely held views] "or widely supported aspects".
In WP:TITLE#Disambiguation, added: [It is not always possible to use the exact title that may be desired for an article, as that title may have other meanings ...]. "Sometimes, this requires a change in the variety of English used; for instance, Lift is a disambiguation page with no primary topic, so we choose elevator as the name of the lifting device.
In (renamed) WP:TITLE#Using minor details to naturally disambiguate articles, added: "Special care should be taken for names translated from other languages and even more so for transliterated titles; there is often no standardized format for the English name of the subject, so minor details are often not enough to disambiguate in such cases. ¶ Certain applications of this policy are often heavily debated; in certain instances, this form of disambiguation may not be sufficient if one article is far more of a primary topic than the other. For instance, an album entitled JESUS would probably have its article located at JESUS (album), with JESUS continuing to be a redirect to Jesus. If the album or other possible uses were deemed by editors to be reasonably likely search results for "JESUS", consensus among editors would determine whether or not JESUS would be the location for the album article, a redirect to Jesus, a disambiguation page, or a redirect to the existing disambiguation page Jesus (disambiguation)."
In WP:V#Burden of evidence, added: [Any material lacking a reliable source directly supporting it may be removed] "and should not be replaced without an inline citation to a reliable source." Changed: "The burden of evidence" [lies with the editor who adds or restores material] to: "The burden of identifying a reliable source". Added: [any editor who later removes the material has an obligation to articulate specific problems that would justify its exclusion from Wikipedia] "(e.g., undue emphasis on a minor point, unencyclopedic content, etc.)."
