Wikipedia:Articles on sources
 | This is an essay. It contains the advice or opinions of one or more Wikipedia contributors. This page is not an encyclopedia article, nor is it one of Wikipedia's policies or guidelines, as it has not been thoroughly vetted by the community. Some essays represent widespread norms; others only represent minority viewpoints. |
Wikipedia should ideally have, so far as its policies and guidelines allow, an article on every substantial publication that is likely to be used as a source for Wikipedia, and on the author and publisher of every such publication.
Why
Articles allow for a central summary of the source from other Wikipedia:reliable sources.
Sources without articles
If Wikipedia does not have such articles in relation to a source, then a readers hoping to use that source are always encouraged to update the article as having a broader knowledge base about reliable sources is especially important to Wikipedia.
