No original research[edit]

Kindly do remember that Wikipedia is an encyclopedia which means that original research is not to be published there.

Wikipedia articles must not contain original research. The term "original research" (OR) is used on Wikipedia to refer to material—such as facts, allegations, and ideas—for which no reliable, published sources exist.[1] This includes any analysis or synthesis of published material that serves to advance a position not advanced by the sources. To demonstrate that you are not adding OR, you must be able to cite reliable, published sources that are directly related to the topic of the article, and directly support the material being presented.

The prohibition against OR means that all material added to articles must be attributable to a reliable published source, even if not actually attributed.[1] The verifiability policy says that an inline citation to a reliable source must be provided for all quotations, and for anything challenged or likely to be challenged—but a source must exist even for material that is never challenged. For example: the statement: "Paris is the capital of France" needs no source, because no one is likely to object to it and we know that sources exist for it. The statement is attributable, even if not attributed.

  • Do not analyze, synthesize, interpret, or evaluate material found in a primary source yourself; instead, refer to reliable secondary sources that do so.
  • Do not base an entire article on primary sources, and be cautious about basing large passages on them.
  • Do not add unsourced material from your personal experience, because that would make Wikipedia a primary source of that material.

  • Wikimedia Commons was launched in September 2004 to provide a central repository for free photographs, diagrams, maps, videos, animations, music, sounds, spoken texts, and other free media. It is a multilingual project with contributors speaking dozens of languages, that serves as a central repository for all Wikimedia projects. You can for example upload images and scientific illustrations here.

Information about the other projects


  1. a b By "exists", the community means that the reliable source must have been published and still exist — somewhere in the world, in any language, whether or not it is reachable online — even if no source is currently named in the article. Articles that currently name zero references of any type may be fully compliant with this policy — so long as there is a reasonable expectation that every bit of material is supported by a published, reliable source.
