The Great God Pan
What is now the first chapter of the novella was published in 1890 in a magazine called "The Whirlwind", while what is now the third chapter of the book was published in the same magazine the following year as a standalone short story called "The City of Resurrections". Machen only viewed the two works as connected after they were finished. Once he decided the two stories were connected, Machen wrote the rest of "The Great God Pan" in a single evening save for its final chapter. Machen did not think of an ending for the tale for months, and in that time believed that the novella would remain unfinished forever. The last chapter was completed in June 1891. Machen sent the novella to the publisher Blackwood, who rejected it, deeming it a clever story that "shrink[s]...from the central idea." It was accepted by John Lane and published in 1894. When published as a book, "The Great God Pan" was accompanied by another Machen tale called "The Inmost Light" which also features a mad scientist and elements of science fiction. The book's cover was illustrated by Aubrey Beardsley.
Gay pulp fiction
Most of the new gay paperbacks were explicitly pornographic, writing designed to provoke sexual responses, rather than literary writing, and they came from small, gay presses, such as the Guild Press, Greenleaf Classics, and the Publisher's Export Company, rather than from mainstream national publishers. For example, Greenleaf (under editor Earl Kemp) published a series of erotic spy parodies called "The Man from C.A.M.P.", written by Victor J. Banis. Banis says once Kemp and Greenleaf proved how much of a market there was for this type of fiction, other publishers soon joined in.
