The Library Company's online exhibition "Philadelphia Gothic: Murders, Mysteries, Monsters, and Mayhem Inspire American Fiction 1798–1854" examines that city's contributions to literary "lurid crime" and includes sections on Edgar Allan Poe, Robert Montgomery Bird, Charles Brockden Brown, George Lippard, and Aaron Burr associate Leonora Sansay (more on Sansay here). Two podcasts associated with the exhibition can be found here.
