sure what we're looking for is reliable sources that means we're looking for guarantees of reliability in the source like having been published in an academic journal further we want to avoid sources that represent only one person's view on the topic since we're obviously not going to have a paragraph on everyone who's ever said anything about hamlet what you've added isn't backed up by a reliable source since from that youtube video we have no idea who this person is why he's talking about hamlet or if anyone else believes what he's saying that's why we want to see academic journals even if his ideas are published in academic journals we'd want to see citations to that work to determine that it's sufficiently notable for an encyclopedia and not just one person's view agtx
