Wikipedia:You are not a reliable source

No matter how knowledgeable you may be, you are not a reliable source for Wikipedia content. The reverse is also true, you are not a reliable source for removal of content supported by a reliable source that you think is in error.
There are several reasons why this is so:
- Readers cannot independently verify your identity.
- Readers cannot independently verify your credentials. See Wikipedia:Reliable sources.
- Readers cannot independently verify your facts. See Wikipedia:Verifiability.
- Readers cannot independently verify your analysis. See Wikipedia:No original research.
What to do if you have a reliable source
If you have a reliable source but don't know how to add a reference, you can put it in your edit summary. Edit summaries have a limit of around 500 characters so you can give more than one source. Better yet, read Help:Referencing for beginners and learn how to add references on your own.
