Of the eighteen people contributing to the forthcoming Cambridge University Press book on progressive rock, sixteen are university-affiliated academics (so it would be reasonable for them to expect to do such things as a part of their employment), one is VP of Education at the Rock and Roll Hall of Fame and Museum, and one is a computer technology order support specialist making the equivalent of about $11 U.S. per hour. Guess which one resents doing academic research and writing for free, given that it has nothing to do with his employment?
