Barlow was interested in printing and after becoming involved in the early 'fan' scene relating to fantasy and science fiction, published several important journals - "The Dragon-Fly" (two issues - October 15, 1935, and May 15, 1936); and "Leaves" (two issues - Summer 1937; Winter 1938/39).

He was also proprietor of his imprint, the Dragon-Fly Press (Cassia, Florida) and under that imprint published two important works by members of the Lovecraft Circle - "The Goblin Tower" (the first verse collection by Frank Belknap Long – Lovecraft helped Barlow set the type for this) and "The Cats of Ulthar", a story by H. P. Lovecraft.
