Books Mentioned in Another Book

We grabbed a few books off the shelf in fiction and nonfiction and skimmed through them to create a short list of books mentioned in other books for our 2019 Reading Challenge. In no particular order, here are books mentioned in books about books, as well as books mentioned in books about book clubs, in novels, in essays, in anthologies, in epigraphs, in indexes we flipped through...and so on. Happy reading!
