At Comic-Con I had the pleasure of meeting Jason Shiga, Eisner award-winning author of Bookhunter. We had one of those mutual fanboy moments - we're both big fans of each other's library comic. Like ours, his began at the web (you can still read it at his website) and made its way to book form. Like me he has a degree in Mathematics. Like Gene he works in a library. So he knows.
