Over the years, I've ended up with a few duplicates of Go World magazine. Extras I have are numbers 42, 48, 49, 93. I also have a hardbound volume containing numbers 31 through 38. The volume contains the full issues except the back covers (front covers are intact; no idea why they didn't keep the back covers.) I would say everything is in very good condition (I'm no book expert, so that's strictly subjective.)
I'm open to any reasonable offer or trade. If trade, let me know what you have that you'd be willing to part with (in terms of English Go literature, that is), and we can haggle. I am missing some issues of the old Go Review, so if you're overstocked on those, let me know and I will tell you which issues I'm short. (Although I suspect that anyone who is overstocked on Go Review probably isn't missing any Go Worlds!) If you want to buy with money, we can haggle over that, too.
PM me if interested.
