This is an essay on copyright violations. 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.

This page in a nutshell: If an article is based on only one source, there may be copyright, original research, and notability concerns.

Articles with a single source may have potential problems with notability, copyright violations, and original research. These articles may also be constructed like a dictionary entry, or have other verifiability issues. Articles relying on a single source should be tagged with the template {{onesource}} at the top of the article to notify editors of the issue. Due to a high probability of copyright infringement and plagiarism within articles relying on a single source, the one source tag should not be removed until multiple sources are utilized to verify content in the article. Even when there are multiple sources, the one source tag may still be appropriate if an article relies too heavily on a single source.
