My paper titled Increasing cooperation among plants, symbionts, and farmers is key to past and future progress in agriculture is now available on-line at the Journal of Bioeconomics, if your library has the right kind of subscription. Otherwise, they want $40 to download the paper. It would be cheaper to buy a hardbound copy of my book. The paper has some new material that's not in the book, of course, but the book is still probably a better deal. Does anyone pay that much to download one paper?
I'm in Saskatoon to give a department seminar and speak at a student-organized symposium. I'll add a web link if I find one, but here's last year's, where Wes Jackson spoke. That could have been an interesting debate.
