There are two editions. The 2d has many corrections and new articles by real experts but carries some of the material from the first, much of which was poorly done.

I've seen bits of this in google books when searching. There is a library discard available, and am wondering if anyone has opinions on the value of this publication. Thanks! Thomas.
