OzWiki

OzWiki is a comprehensive guide to L. Frank Baum's Oz universe that all started with the 1900 book The Wonderful Wizard of Oz and got a popularity boost thanks to the 1939 MGM film The Wizard of Oz. Despite there being a number of articles in the double digits and the website being written mostly by one researcher, the site truly is comprehensive; some of the articles on the site are extremely detailed timelines and overviews of this wondrous fantasy land, so if the number of articles disappoints you, wait until you see how detailed the articles are; it helps that the articles are about public domain books, so you can instantly go read the book the article is talking about without having to purchase anything. This wiki is full of little known facts about the Oz universe; as many people are familiar with the film, and a significant number of people are familiar with the first book, many people are not familiar with a lot of the sequels, so you will be surprised when you learn that there was a book where Dorothy and her family go live in Oz, or that Dorothy stopped appearing in the books midway through the original Baum series. This really is the Wonderful Wiki of Oz!
