The word "source" in Wikipedia has three meanings: the work itself (a document, article, paper, or book), the creator of the work (for example, the writer), and the publisher of the work (for example, ''The New York Times''). All three can affect reliability.   

Base articles on reliable, third-party, published sources with a reputation for fact-checking and accuracy. Source material must have been published (made available to the public in some form); unpublished materials are not considered reliable. Sources should directly support the material presented in an article and should be appropriate to the claims made. The appropriateness of any source depends on the context. In general, the best sources have a professional structure in place for checking or analyzing facts, legal issues, evidence, and arguments; as a rule of thumb, the greater the degree of scrutiny given to these issues, the more reliable the source.

Where available, academic and peer-reviewed publications are usually the most reliable sources, such as in history, medicine, and science. But they are not the only reliable sources in such areas. Material from reliable non-academic sources may also be used, particularly if it appears in respected mainstream publications. Other reliable sources include university-level textbooks, books published by respected publishing houses, magazines, journals, and mainstream newspapers. Electronic media may also be used, subject to the same criteria.  See details in ''[[Wikipedia:Identifying reliable sources]] and [[Wikipedia:Search engine test]]''

===Newspaper and magazine blogs===
{{policy shortcut|WP:NEWSBLOG}}
Several newspapers host columns they call [[blog]]s. These are acceptable as sources if the writers are professionals and the blog is subject to the newspaper's full editorial control. In March 2010, the Press Complaints Commission in the UK ruled that journalists' blogs hosted on the websites of newspapers or magazines are subject to the same standards expected of comment pieces in that organization's print editions.<ref>Plunkett, John. [http://www.guardian.co.uk/media/2010/mar/29/rod-liddle-pcc-spectator "Rod Liddle censured by the PCC"], ''The Guardian'', March 29, 2010.</ref> Where a news organization publishes an opinion piece, attribute the writer (e.g. "Jane Smith has suggested..."). Never use posts left by readers as sources. For blogs that are not reliable sources, [[#Self-published sources|see below]].

To discuss the reliability of a specific source for a particular statement, consult the [[Wikipedia:Reliable sources/Noticeboard|reliable sources noticeboard]], which seeks to apply this policy to particular cases. For a guideline discussing the reliability of particular ''types'' of sources, see [[Wikipedia:Identifying reliable sources]] (WP:IRS). In the case of inconsistency between this policy and the [[WP:IRS]] guideline, or any other guideline related to sourcing, the policy has priority.
