All of CJ Cherryh’s stuff, Ghoster (Lee McKee), The heechee saga, all the old (60’s through now) scifi short story anthologies, the Star of the guardians trilogy. I used to trawl used book stores (when that was a thing) with a backpack full of trade ins . Used the anthologies to find authors, etc etc. Something for something, What about you?
Robert Asprin is a new one for me, I’ll have to look around, thanks!
