U.S. Documents Masterfile Content

U.S. Documents Masterfile is your one-stop resource for American public and political documents from 1774 to present day. It simplifies the process, through extensive integration of more than 30 historical indices—from the earliest records of the Continental Congress through contemporary federally-funded research data—many linked to full-text targets.


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.

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.
