Historical and Contemporary Data

U.S. Documents Masterfile bridges the divide between historical federal information and the more systematic cataloguing of U.S. federal documents beginning in 1976.

In addition to materials published through the GPO, U.S. Documents Masterfile also contains a wealth of Non-GPO federal data, which makes up as much as 55% of federal output.

Lesser known and ‘fugitive’ documents are also included, as well as allowing for queries via Superintendent of Document (SuDoc) numbers.



Enhanced Search

Advanced searching methods bring new layers of authority to your research.

The Enhanced Search feature in U.S. Documents Masterfile expands your search results by simultaneously searching related terms such as synonyms, word endings, and antiquated words of the same meaning.

It will include common variations on words like 'emancipation emancipate emancipator' and outdated word variations like 'burma myanmar' and 'obesity corpulence'.

Making Sense of Gov’t Documents…

Researching U.S. federal data is challenging, even for experts. Documents are disorganized and difficult to pinpoint.

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.

Non-GPO materials include a vast array of federally-funded research for those studying biology, economics, engineering, the arts, political science, or anthropology. The coverage is vast and ever-growing.

Filtering options can simplify your search to narrow by Agency, SuDoc Number, date of publication, and more.
