New Digitally Authenticated Collections in FDSys
The U.S. Government Printing Office (GPO) has recently announced on its Federal Digital System (FDSys) blog that several collections have been digitally signed and authenticated, including the Weekly and Daily Compilations of Presidential Documents. Several of the FDSys collections are already authenticated with digital signatures, including the Congressional Directory and United States Statutes at Large.
What does digital authentication mean? Documents published online can be manipulated or copied, so there is a risk of finding inaccurate government information online. The U.S. GPO adds digital authentication signatures to ensure that its online publications have not been altered or copied. When you open any digitally authenticated document on GPO Access or FDSys, you will see a pop-up box giving you detailed information about the document's authentication status.
You can find out more about digital signatures of government publications at the U.S. GPO Authentication page.
