I found Molly White's video here really useful for helping me understand the Reliable Sources policy: https://blog.mollywhite.net/become-a-wikipedian-transcript/
> The way we determine reliability is typically based on the reputation for editorial oversight, and for factchecking and corrections. For example, if you have a reference book that is published by a reputable publisher that has an editorial board and that has edited the book for accuracy, if you know of a newspaper that has, again, an editorial team that is reviewing articles and issuing corrections if there are any errors, those are probably reliable sources.
Yeah. Also, if a specific source is used a lot, it often gets put on a discussion where people vote on how reliable it is. If it's considered unreliable, the use of it will be banned.
