The following list contains articles, stories and novels written by Philip José Farmer with another writer. In some cases they worked on the story at the same time, in some cases Farmer started it and someone else finished it.
THE BALLAD OF HILARY BOONE, with Randall Garrett
Unpublished, early 1950s
Based on a song of the same name by pulp writer Charlie Tanner, this novel by Farmer and Garrett was about a space pirate. It was sold to Startling Stories but the magazine folded before serializing the story. The manuscript was sent out again and subsequently lost.
Osiris on Crutches, with Leo Queequeg Tincrowder
A humorous story about the god Osiris and a meeting, with Leo Queequeg Tincdrowder.
The Remarkable Adventure, with Beverly Friend
In this long article they discuss how many adventure stories are centered around a journey and how science fiction novels more than other contemporary stories are similar to the ancient epics like THE ODYSSEY.
THE CATERPILLAR'S QUESTION, with Piers Anthony
Written with Piers Anthony. They alternated writing sections, mailing them back and forth. I cannot tell where one writer ends and the other begins. Some scenes feel like Farmer's work but the book as a whole does not. Not to say that is bad, the book is very good. REVIEWS

THE CITY BEYOND PLAY, with Danny Adams
Have you ever heard of the The Society for Creative Anachronism or perhaps been to a Renaissance Festival? Imagine a future where the SCA owns a large valley in California. If you choose to live there you step back in time to the middle ages, not the way they were, but the way they should have been (indoor plumbing for starters). A murderer on the run from the police gets fake id papers and joins the community. Will he be able to climb the social ladder without giving himself away?
Phil Farmer began this novel in the early 1970s, writing the first chapters and an outline of the remainder, and his grand-nephew Danny Adams finished writing the story in 2005. REVIEWS
Getting Ready to Write, with Paul Spiteri
This polytropical paramyth was started by Farmer, mostly likely in the 1970s, and completed by Spiteri for Farmerphile: The Magazine of Philip José Farmer. The protagonist is a writer, who descends to his basement office to write, but is continually distracted by one thing after another, each obstacle more fanciful than the rest.

THE EVIL IN PEMBERLEY HOUSE, with Win Scott Eckert
Start with your typical "Girl running from Castle" Gothic novel, add in the literary pedigree of Jane Austen, action worthy of the greatest heroes in the Wold Newton family, and color it all erotic. Not since A FEAST UNKNOWN has Phil turned a convention on its ear like this.
Phil Farmer began this novel in the early 1970s, writing the first chapters and an outline of the remainder, and Wold Newton expert Win Scott Eckert finished writing the story in 2008.
Kwasin and the Bear God, with Christopher Paul Carey
After completing the novel THE SONG OF KWASIN, from Philip José Farmer's outline for the third volume in the Khokarsa series, co-author Christopher Paul Carey discovered a second, alternate outline. While it was similar to the one he had already used, it did include a side adventure, which became the novella, Kwasin and the Bear God.

THE SONG OF KWASIN, with Christopher Paul Carey
The concluding volume to the Khokarsa series (which began with HADON OF ANCIENT OPAR and FLIGHT TO OPAR), co-written with Christopher Paul Carey. This third volume shifts the series from Hadon to his anti-hero cousin, the exiled Giant Kwasin. We follow Kwasin as he tries to redeem himself and help save an empire.
DAYWORLD: A HOLE IN WEDNESDAY, with Danny Adams
Begun by Farmer and completed by Danny Adams. Set some time before the events in the original trilogy, the novel nonetheless has direct links to the acclaimed series, exploring the developing world and antecedent characters who vigorously challenge the life in which they find themselves trapped.
