References on the Wiki are basically footnotes. It's a way of citing information from a reputable source so that information that is likely to be disputed is verifiable. For instance, Elsa and Anna's birthdays are not actually stated in the film, but since the co-director, Jennifer Lee, tweeted their birthdays, we can use the information in Elsa and Anna's articles so long as it is properly cited :)
