Halloween is here, and all things spooky and scary are being honored—especially in the worlds of literature and libraries. On Episode 55 of the newly named Call Number with American Libraries, we speak with Matt Ruff, author of Lovecraft Country, and Elizabeth Campbell Denlinger, curator of the Carl H. Pforzheimer Collection of Shelley and his Circle at New York Public Library, about the collection’s materials on Frankenstein author Mary Shelley.
