A while ago I had a patron who was looking for metafiction picture books for a children's literature class. I had so much fun looking up titles that could work that I kept going long after (and I mean LONG after) finding enough books for him. I put together a list of books for the rest of my staff in case we get this question again and I'm sharing with you all too. I will note that this in no way a complete list of all metafiction books but simply ones we happen to own at my branch. I hope this will be useful for reference and collection development purposes. I happen to be a fan of metafiction myself, so please share in the comments if you have a favorite title not on the list and I'd love to read it!
To start us off, I loved the definition of "metafiction" from What Do We Do All Day: A metafictional text is one that subverts traditional, straightforward storytelling.
Okay, here we go!
