+
+"Wikipedia articles must not contain original research. The phrase "original research" (OR) is used on Wikipedia to refer to material—such as facts, allegations, and ideas—for which no reliable, published sources exist.[a]"
+"(This policy of no original research does not apply to talk pages and other pages which evaluate article content and sources, such as deletion discussions or policy noticeboards.) "
+"The prohibition against OR means that all material added to articles must be attributable to a reliable, published source, even if not actually attributed.[a]"
