Hello, I wanted to know if there are additional writings about Narnia from C.S. Lewis, things like short stories, appendices, poems etc. I'm not really looking for interpretations of his writings, influences or how he went about doing it (but more then happy to have it if included/accompanying what I'm looking for). I'm interested in finding finished and unfinished writings additional to the 7 novels about Narnia that give background info, other stories, info that ties up loose ends etc. It doesn’t have to be written by C.S. Lewis himself as long as it’s directly from him or corresponding to a close relationship with him. I'm not sure how much is out there but I would appreciate it if someone could point me in the right direction or tell me if/what such pieces exist. I've looked around for this info myself but I'm not having much luck figuring it out. There doesn't appear to be as much compared to say all of Tolkien's additional writings about Middle Earth but that's the sort of thing I'm looking for. I want to soak in as much of Narnia as I can. Thank you very much for taking the time to read this, I hope you have a lovely day.
