Queer cowboys!

I need to do research for a story I'm writing, so I'm collecting the relevant books I find here :) I will feature a range of fiction and non-fiction books about the real history and the fun imaginary worlds of queer western books. Suggestions always welcome!

p.s. there may be non-queer westerns or history of that era that make their way on here for research sake, but the goal is ultimately to bring more gay cowboys (gender neutral) into the world
