In addition to the various journals he published, including The Vagrant, The Recluse, The Revenant, "The Ghost", and Monadnock, Cook published books under the Recluse Press imprint. Some of them were by members of the Lovecraft Circle, such as Samuel Loveman, Frank B. Long Jr. (Frank Belknap Long), Donald Wandrei, Walter J. Coates (proprietor of The Driftwind Press), and Lovecraft himself.
