Wikipedia:Potentially unreliable sources

Wikipedia's requirement for writing articles is "verifiability, not truth". We rely on what is written in external sources to write this encyclopedia, yet not all sources are equal. The guideline Wikipedia:Identifying reliable sources gives general advice on what is and isn't a reliable source; this essay aims to analyse specific examples of sources that might initially appear to be reliable, yet may not be. If in doubt about a source, discuss this at the reliable sources noticeboard.
