It is titled "New Earths -- Restructuring Earth and Other Planets" (Stackpole, 1981) and discusses possible terraforming methodologies. It is largely based on the presentations and discussions at the terraforming colloquium at the Houston Lunar and Planetary Science Conference, March 1979. I've just started it but scanned through it first and can recommend it as readable and interesting. One section discusses the mirrors-in-orbit we recently had some comments about. Will Martin
