Gary King and the Methodology Organized Section of APSA have certainly done the profession an important service by point out some of the deficiencies of our current practices on archiving data sets. For 40 years now, political scientists have grumbled about the lack of availability of major data sets (with the McClosky (1960) data being perhaps the most prominent example), so it is high time that the profession as a whole adopts some guidelines and standards. King's article in this journal is an important way to start the discussion.
