"As of today, March 16, 2012, the transition from GPO Access to GPO's Federal Digital System (FDsys) is complete. FDsys now is GPO's only Web site for online official and authentic Government information from all three branches of the Federal Government. After ushering GPO into the online world 16 years ago, GPO Access has been archived and taken off line. As part of the transition process, no new content has been added to GPO Access since November 2011."
