I think the best analogy for this kind of copying is our article on Star Wars opening crawl We don t include an actual reprint of the text We include whatever information there is around the text We might even summarize the text but we don t repeat the text not even with a word or two changed That s how we cover something encyclopedically without getting into copyright issues Admittedly there is some stuff written about the Narnia timeline I don t think it s enough to warrant an article and I don t think it justifies copyright violation I m interested to see what a resident copyright expert would say though
