[Updated 8 Aug. 2011]
Work on Volume V is proceeding steadily; we expect to see it in print by August 15. Volume V is now available on Amazon.com. We appreciate the fact that there are those who are anxiously waiting for later volumes to appear; we can only offer our assurances that we are working diligently.
In the meantime, we wanted to give our readers a look at the contents of the entire set as it will stand when finished. (And also put to rest the recurring misconception that we have either completed or are near the completion of this project).
