The U.S. GOVERNMENT PUBLISHING OFFICE (GPO) is the official, digital and secure source for producing, protecting, preserving and distributing the official publications and information products of the Federal Government.
GPO provides public access to the official publications and information of the Government. GPO’s mission can be traced to the requirement in Article I of the Constitution that each House keep a journal of its proceedings and from time to time publish the same.
When GPO signs and certifies a digital document, a blue ribbon icon appears right beneath the top navigation menu and also in the Signature Panel within Adobe Acrobat or Reader. When users print a document that has been signed and certified by GPO, the Seal of Authenticity will automatically print on the document, but the ribbon will not print.
