Thanks for reading! Yes, absolutely it needs to change. The research I did mainly used the Disney Fandom unofficial website, which although comprehensive is a little like Wikipedia. So I had to fact-check a lot of the information on the site via other sources (hence the paragraph at the bottom of the article). Research definitely took a long time! If this piece was commissioned for a magazine or journal, I'd like to make it longer and research more extensively – actively fact-checking everything ever made by Disney to look for female contributions, as there are bound to be one or two obscure Disney things that didn't make the fandom website. But this source is so far the best comprehensive list I could find anywhere, so that's what this article is based on.
