Making Sense of Gov’t Documents…

Researching U.S. federal data is challenging, even for experts. Documents are disorganized and difficult to pinpoint. Less than 45% of all US federal publications come through the US Government Publications Office (GPO).

U.S. Documents Masterfile is the only outlet offering a single search for indexes and records for nearly 250 years of U.S. federal government information - with GPO and Non-GPO materials.
