Now you know <i>how</i> to add sources to an article, but <i>which</i> sources should you use? </p><p>The word "source" in Wikipedia has three meanings: the work itself (for example, a document, article, paper, or book), the creator of the work (for example, the writer), and the publisher of the work (for example, Cambridge University Press).

They tend to have an editorial process with multiple people scrutinizing work before it is published. <a href="/wiki/Wikipedia:SCHOLARSHIP" class="mw-redirect" title="Wikipedia:SCHOLARSHIP">Academic and peer-reviewed publications</a> are usually the most reliable sources. Other reliable sources include university textbooks, books published by respected publishing houses, magazines, journals, and news coverage (<a href="/wiki/Wikipedia:Reliable_sources#Statements_of_opinion" title="Wikipedia:Reliable sources">not opinions</a>) from <a href="/wiki/Wikipedia:NEWSORG" class="mw-redirect" title="Wikipedia:NEWSORG">mainstream newspapers</a>. </p><p><b><a href="/wiki/Wikipedia:Self-published_sources" class="mw-redirect" title="Wikipedia:Self-published sources">Self-published media</a></b>, where the author and publisher are the same, are usually <i>not</i> acceptable as sources. These can include newsletters, personal websites, press releases, patents, open wikis, personal or group blogs, and tweets. However, if an author is an established expert with a previous record of third-party publications on a topic, their self-published work <i>may</i> be considered reliable for that particular topic. </p><p>Whether a source is usable also depends on context. Sources that are reliable for some material are not reliable for other material. For instance, otherwise unreliable self-published sources <a href="/wiki/Wikipedia:Verifiability#Self-published_and_questionable_sources_as_sources_on_themselves" title="Wikipedia:Verifiability">are usually acceptable</a> to support uncontroversial information about the source's author. You should always try to use the best possible source, particularly when writing about <b><a href="/wiki/Wikipedia:BLP" class="mw-redirect" title="Wikipedia:BLP">living people</a></b>. </p><p>These are general guidelines, but the topic of reliable sources is a complicated one, and is impossible to fully cover here.
