A work-around that the Federal Depository Libraries created to ensure Federal Docs (scanned by Google) remain available to the public through the CIC university consortium. 

"The libraries of the CIC universities are partnering with Google to digitize a comprehensive collection of U.S. Federal Documents. It is believed this collection will comprise between 1 and 1.5 million volumes. Digital facsimiles of successfully scanned Federal Documents from CIC institutions will be accessible through Google Book Search, with copies also being returned to the HathiTrust Digital Repository <http://www.hathitrust.org> , where public domain material can be universally accessed."
