Paper Golem would like me to alert you to some exciting new developments.
Both Cucurbital 2 and Curbital 3 are available electronically, as well as in hard cover and soft cover. Here's where you can find them.
Amazon has these exclusively for 90 days, so when there are other electronic links, we'll post 'em.
If you're like me, and you don't do Amazon, Barnes and Noble can also help you out.
Watch for a book contest soon.
