A BLAST FROM THE IAOS PAST: I recently ran across a copy of the IAOS Obsidian Bibliography from 1993. This was a freebie for all IAOS members at the time and was our one and only IAOS Occasional Paper. To download a copy of this now charmingly obsolete pre-WWW research tool, head over to the IAOS online library and look for Skinner and Tremaine (1993).
