Wikipedia:Merging

For the WikiProject, see Wikipedia:WikiProject Merge.
This page is about merging of articles. For merging and splitting of categories, see WP:Category intersection.
"WP:DA" and "WP:Duplicate article" redirect here. For articles with duplicated content, see WP:Content forking. For the list of articles that have not been edited in the longest time, see Wikipedia:DUSTY.

A merger is a non-automated procedure by which the contents of two or more pages are united within a single page. Merging creates a redirect from the source page(s) to the destination page, with some or all of the content copied and pasted into that page. Editors should use their discretion to decide whether or not a discussion should occur before spending the time to merge articles.

Do not use the discussion procedure described below to propose:

Reasons for merger

There are several good reasons to merge pages:

  1. Duplicate: There are two or more pages on exactly the same subject, with the same scope.
  2. Overlap: There are two or more pages on related subjects that have a large overlap. Wikipedia is not a dictionary; there does not need to be a separate entry for every concept. For example, "flammable" and "non-flammable" can both be explained in an article on flammability.
  3. Text: If a page is very short and is unlikely to be expanded within a reasonable amount of time, it often makes sense to merge it with a page on a broader topic. For example, parents or children of a celebrity who are otherwise unremarkable are generally covered in a section of the article on the celebrity (and can be merged there).
  4. Context: If a short article requires the background material or context from a broader article in order for readers to understand it. For example, minor characters from works of fiction are generally covered in a "List of characters in <work>" article (and can be merged there); see also Wikipedia:Notability (fiction).

Merging should be avoided if:

  1. The resulting article is too long or "clunky"
  2. The separate topics could be expanded into longer standalone (but cross-linked) articles
  3. The topics are discrete subjects warranting their own articles, even though they might be short

Merging—regardless of the amount of information kept—should always leave a redirect (or, in some cases, a disambiguation page) in place. This is often needed to allow proper attribution through the edit history for the source page. Superfluous redirects do not harm anything, and they can be helpful in finding articles, e.g. from alternative names.

You may find that some or all of the information to be merged is already in the destination page. That is fine; you can feel free to delete the redundant information and only add new material. If there is no information to be added to the destination page, you can simply redirect the other page there, but please make this clear in the edit summary.
