Westerns = the old man genre. I'm weeding them and most of them were published before I was born in the 70's. This one called Halter-Broke by John Reese has some writing in it: a very wierd (underlined 2x) story.
And Sodbuster by Gary McCarthy was (same handwriting) excellent.
I've decimated about 1/2 of the collection, and I think the guy initialed every one he read. Along with comments usually.
