Wikipedia:When to cite

The list of featured-article criteria calls for inline citations where appropriate. The English Wikipedia's Verifiability policy requires inline citations for quotations, whether using direct or indirect speech, and for material that is challenged or likely to be challenged. Editors are also advised to add in-text attribution whenever a source's words are copied or closely paraphrased. You can make clear which sources support your article using:

  • INCITE: Cite your sources in the form of an inline citation after the phrase, sentence, or paragraph in question.
  • INTEXT: Add in-text attribution whenever you copy or closely paraphrase a source's words.
  • INTEGRITY: Maintain text–source integrity by placing inline citations in a way that makes clear which source supports which part of the text.
