A topic is presumed to merit an article if:

If a topic has received significant coverage in reliable sources that are independent of the subject, it is presumed to be suitable for a stand-alone article or list.

If a topic does not meet these criteria but still has some verifiable facts, it might be useful to discuss it within another article.

The criteria applied to article creation/retention are not the same as those applied to article content. The notability guidelines do not apply to article or list content (with the exception that some lists restrict inclusion to notable items or people). Content coverage within a given article or list (i.e. whether something is noteworthy enough to be mentioned in the article or list) is governed by the principle of due weight and other content policies. For additional information about list articles, see Notability and lists and Lead and selection criteria.

The common theme in the notability guidelines is that there must be verifiable, objective evidence that the subject has received significant attention from independent sources to support a claim of notability.

No subject is automatically or inherently notable merely because it exists: The evidence must show the topic has gained significant independent coverage or recognition, and that this was not a mere short-term interest, nor a result of promotional activity or indiscriminate publicity, nor is the topic unsuitable for any other reason. Sources of evidence include recognized peer-reviewed publications, credible and authoritative books, reputable media sources, and other reliable sources generally.

The absence of sources or citations in an article (as distinct from the non-existence of sources) does not indicate that a subject is not notable. Notability requires only the existence of suitable independent, reliable sources, not their immediate presence or citation in an article. Editors evaluating notability should consider not only any sources currently named in an article, but also the possibility or existence of notability-indicating sources that are not currently named in the article. Thus, before proposing or nominating an article for deletion, or offering an opinion based on notability in a deletion discussion, editors are strongly encouraged to attempt to find sources for the subject in question and consider the possibility of existent sources if none can be found by a search.
