 		<meta property="se:production-notes">Spine order from https://en.wikipedia.org/wiki/Edgar_Allan_Poe_bibliography#Tales. “The Balloon-Hoax” omitted from this collection as it’s a hoax article and not a piece of short fiction. Typogrify currently breaks General A. B. C.’s name, and an explicit layout in “The Gold-Bug,” so isn’t safe to run against every story.</meta>
