Wikipedia:Verifiability

Wikipedia:Verifiability is a guideline that states all information added to Wikipedia must be backed up by reliable, published sources. This means that statements should be able to be checked and confirmed by others through reputable references, such as books, scholarly articles, or established news outlets. The purpose is to ensure the accuracy and credibility of the content, preventing the spread of false or unverifiable information. If a claim cannot be supported by reliable sources, it should be removed or marked accordingly. This helps keep Wikipedia a trustworthy and neutral platform for knowledge.
