Interesting, I've never heard of this one. It seems like Campbell is one of those few literary voices in the early 20th century who wasn't all that optimistic about the rise of modern technology. Many fiction-writers at the time (H.G. Wells comes to mind) had an almost utopian view on the future, because of the advent of technology. Few writers went against the grain; one who does come to mind is E.M. Forster, and his 'the machine stops', who posits that an over-reliance on technology will doom humanity.
Good luck on keeping up the 1-book-a-week tempo. I won't be able to manage, that's almost certain.
The only work I read form H.G Wells was time machine. It's interesting that I have heard a little about Campbell even after reading Twilight. Maybe he's that quiet voices among many famous authors at the time. One book a week is certainly challenging but so far, I can make a bit of time reading time.
