Wikipedia:Training/core/Notability

Notability Is the subject of the article you want to work on notable enough for an encyclopedia? This guideline helps to clarify the notability question. In some cases, you may need to justify to other Wikipedians why the article topic is notable and should remain in Wikipedia. Coverage in published, reliable, secondary sources that are entirely independent of the subject, and which treat the subject in substantive detail is the key to notability. Thousands of new Wikipedia articles are started every day. Volunteer Wikipedia editors work hard to review each of these pages to determine whether they are appropriate for an encyclopedia. Notability is one of the key criteria for their decisions.
