Before information is used or cited, it is important to check out evidence found in the content of the page and external pages that link to it. Fact-checking and checking references can help to determine if information can be trusted.
Evidence about the content, author, publisher, dates and 'links from' can be considered internal evidence, mainly about the source and content of the information. External evidence can inform the accuracy and credibility of the content of the information. Helpful external evidence tends to be:
Facts that can be verified using external sources
Information on the same subject written by other authors
Reviews of the information by other authorities
Third parties that demonstrate confidence in the information
