The U.S. Government Printing Office is the Federal Government’s primary centralized resource for gathering, cataloging, producing, providing, preserving, and authenticating published information in all forms, both today and in the future. This mission continues to be the inherent function GPO carries out on behalf of the public.
A key component of that mission is performed every day by private-sector printing contractors doing business with the GPO. Castle Press is one of those private-sector printing contractors with a Contractor Number of 040-17685.
