Here is a short listing of books written entirely about Philip José Farmer, including two well-known bio/bibliographic studies, a collector's guide written by Mike Croteau, and program books for two celebrations of Farmer's life and work.
STARMONT READER'S GUIDE 3, by Mary T. Brizzi
There is a short biography, an alphabetical listing of books and stories by Farmer as well as about Farmer. Most of the guide is dedicated to discussing Farmer's major series and themes in depth.

PHILIP JOSÉ FARMER'S MAGIC LABYRINTH, by Edgar L Chapman
Similar to the Starmont Reader's Guide in that it has a short biography and (incomplete) bibliography but mostly covers Farmer's major works. Since it was printed later than the SRG it covers more of his material and, I think, does a better job.
