A merger is the process of uniting two or more pages into a single page. It is done by copying some or all content from the source page(s) into to the destination page and then replacing the source page with a redirect to the destination page.

Any editor can perform a merger. No permission or discussion is needed if you think the merge is uncontroversial; just do it (but it might get reverted). Otherwise, the merge should be first proposed and discussed, as detailed below.

When performing a merger, one should remember to reconcile talk pages, and to attribute copied content, as required by Wikipedia's license. At minumum, this means adding words "Merged content to/from [[page]]" to edit summaries.See How to merge below for details.

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. Short 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 would be 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
