The site navigation utilizes arrow, enter, escape, and space bar key commands. Left and right arrows move across top level links and expand / close menus in sub levels. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site rather than go through menu items.
The Government Printing Office was created by Congress in June of 1860 as an agency of the legislative branch of the Federal Government. GPO is the Federal Government's primary centralized resource for gathering, cataloging, producing, providing, authenticating, and preserving published information in all its forms. GPO is also responsible for the production and distribution of information products and services for all three branches of the Federal Government.
In December 2014 legislation was passed that changed the agency's name from Government Printing Office to Government Publishing Office.
