Title: Venus on the Half-Shell and Others
Passage: Venus on the Half-Shell and Others (ISBN  ) is a collection mostly of science fiction author Philip José Farmer's pseudonymous fictional-author literary works, edited by Christopher Paul Carey and published in 2008.  Farmer describes a fictional-author story as "a tale supposedly written by an author who is a character in fiction."  Carey, who had access to Farmer's correspondence while editing the book, reveals in his introduction that in the early to mid-1970s Farmer planned to edit an anthology of fictional-author stories by other writers.  Farmer solicited fictional-author stories from authors such as Arthur Jean Cox, Philip K. Dick, Leslie Fiedler, Ron Goulart, Howard Waldrop, and Gene Wolfe, urging them to submit their stories to venues such as "The Magazine of Fantasy and Science Fiction".  Only Cox, Waldrop, and Wolfe completed their stories and had them published, although Philip K. Dick's never realized fictional-author story "A Man for No Countries" as by Hawthorne Abendsen is said to have led Dick to write his posthumous novel "Radio Free Albemuth".  In the end, Farmer's fictional-author anthology never materialized.
