Is there a general term for novels (or other fictions) that contain/mention themselves? I mean, the novel is called The Book of Glum, and it's about someone who turns out to be writing or reading a book called The Book of Glum, or we're at least given to know that this is a world where The Book of Glum already exists?
Also, is there decent existing discussion (in journals or elsewhere) of this phenomenon?
