An excerpt is a transclusion of part of an article (usually the lead section) into another article. Excerpts are made using the Template:Excerpt and have several benefits:

  • Increased coherence of the encyclopedia, by reducing outdated and contradictory information
  • Reduced maintenance, because improving the transcluded article also improves the transcluding ones
  • Better collaboration, by channeling editors to the transcluded article to reduce parallel and duplicated work
  • Improved content, by merging multiple sections covering the same topic

Excerpts are often useful in sections with a main article. Such sections are usually summaries of the main article, so their original content (if any) can be merged into the main article and the section replaced for an excerpt of the lead section. Other uses are avoiding copy-paste of population tables, tournament scores, episode lists and other such resources.

Excerpts are an example of the Don't Repeat Yourself principle being applied. Wikidata, Wikimedia Commons, templates and even wikilinks are other examples of this principle being applied.
