Literary Criticism
Which episodes raised this book?
Author, year and identifiers come from Google Books, matched by title. The title is as the show notes wrote it. The notes say which books an episode touched, not who raised each one, so the people named above were in the room rather than confirmed as the recommender. How this is built.
