Type- and manuscript letters received from Emanuel, and carbon copies of letters sent to him in return. The letters are predominantly about the development, writing and publication of stories by Emanuel under his own name or one of his pseudonyms, as well as serializations by other authors Emanuel admired or drew inspiration from, and rates paid for published stories. Exchanges of a more personal nature appear through out, touch on topics such as the potential purchase of land, plans for a trip to Quebec or Sault Ste. Marie, etc.
