I have the black book, 3rd edition. On the cover page it states "The purpose of the third edition is to update the second edition to be consistent with the most current AISC publications. In particular, this edition references the following: 2005 AISC specification for structural steel buildings, 2005 AISC Seismic provisions for structural steel buildings"
I don't have the 2nd edition personally, but I hope this helps.
