According to NPOV, information must be presented When editing a Wikipedia page, it might be difficult to adhere to the fundamental idea of honesty, without prejudice, and with the freedom for readers to form their own opinions based on trustworthy sources. Wiki page update services are required to ensure that the material they supply complies with this rule while updating a Wikipedia page.

Choosing sources with a track record for neutrality and dependability takes serious study.
