Despite it’s title, THE BEST WESTERN STORIES OF ED GORMAN, edited by Bill Pronzini and Martin H. Greenberg, is the same book Richard Prosch posted on here. The edition I have is a large print one published in 1995 in the United Kingdom. Different cover, but the same otherwise in content and story order.
Richard does a wonderful job of commenting on the individual pieces. You should read his post.
My favorites include the Leo Guild story(the novels are fine indeed), Pards, and the piece on Roy Rogers. I’m of that last generation that watched and loved Roy, and his ilk, before they seemed to disappear from television and movies. No, cowboys didn’t dress that, no version of the celluloid westerner for that matter, but who cares.
It’s a set of stories worth digging up if one hasn’t already added it to their library.
