I dont want to reopen the issue as the issue was never actually solved Wikipedia policies are pretty clear on what consititutes a valid source for any topic and childrens books and books not about the specific topic but that happen to mention it as an aside based upon no real knowledge of the topic clearly do not count Instead of just blind reverting changes Id like someone to try to come up with some sort of justification within Wikipedia policies that would make including such weak and nonacademic references as sources Whenever a source is in question it should be up to the person who wants them to stay to provide reasons not to just keep them come hell or high water because of some peoples bias against editors who arent signed in These changes were badly needed and seemingly the only reason they were undone was by one editor who thinks he WPOWNs the article and others who violated WPAGF and assumed that an anon user must be up to no good
